CVE-2020-11494 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2022-04-29 2.1 LOW 4.4 MEDIUM
An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It allows attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4.
CVE-2019-19039 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2022-04-29 1.9 LOW 5.5 MEDIUM
** DISPUTED ** __btrfs_free_extent in fs/btrfs/extent-tree.c in the Linux kernel through 5.3.12 calls btrfs_print_leaf in a certain ENOENT case, which allows local users to obtain potentially sensitive information about register values via the dmesg program. NOTE: The BTRFS development team disputes this issues as not being a vulnerability because “1) The kernel provide facilities to restrict access to dmesg - dmesg_restrict=1 sysctl option. So it's really up to the system administrator to judge whether dmesg access shall be disallowed or not. 2) WARN/WARN_ON are widely used macros in the linux kernel. If this CVE is considered valid this would mean there are literally thousands CVE lurking in the kernel - something which clearly is not the case.”
CVE-2020-12656 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2022-04-29 2.1 LOW 5.5 MEDIUM
** DISPUTED ** gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c in the rpcsec_gss_krb5 implementation in the Linux kernel through 5.6.10 lacks certain domain_release calls, leading to a memory leak. Note: This was disputed with the assertion that the issue does not grant any access not already available. It is a problem that on unloading a specific kernel module some memory is leaked, but loading kernel modules is a privileged operation. A user could also write a kernel module to consume any amount of memory they like and load that replicating the effect of this bug.
CVE-2020-0543 6 Canonical, Fedoraproject, Intel and 3 more 719 Ubuntu Linux, Fedora, Celeron 1000m and 716 more 2022-04-28 2.1 LOW 5.5 MEDIUM
Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
CVE-2020-12864 3 Canonical, Opensuse, Sane-project 3 Ubuntu Linux, Leap, Sane Backends 2022-04-28 3.3 LOW 4.3 MEDIUM
An out-of-bounds read in SANE Backends before 1.0.30 may allow a malicious device connected to the same local network as the victim to read important information, such as the ASLR offsets of the program, aka GHSL-2020-081.
CVE-2020-13696 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2022-04-28 3.6 LOW 4.4 MEDIUM
An issue was discovered in LinuxTV xawtv before 3.107. The function dev_open() in v4l-conf.c does not perform sufficient checks to prevent an unprivileged caller of the program from opening unintended filesystem paths. This allows a local attacker with access to the v4l-conf setuid-root program to test for the existence of arbitrary files and to trigger an open on arbitrary files with mode O_RDWR. To achieve this, relative path components need to be added to the device path, as demonstrated by a v4l-conf -c /dev/../root/.bash_history command.
CVE-2020-3812 3 Canonical, Debian, Netqmail 3 Ubuntu Linux, Debian Linux, Netqmail 2022-04-28 2.1 LOW 5.5 MEDIUM
qmail-verify as used in netqmail 1.06 is prone to an information disclosure vulnerability. A local attacker can test for the existence of files and directories anywhere in the filesystem because qmail-verify runs as root and tests for the existence of files in the attacker's home directory, without dropping its privileges first.
CVE-2019-20810 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2022-04-28 4.9 MEDIUM 5.5 MEDIUM
go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c in the Linux kernel before 5.6 does not call snd_card_free for a failure path, which causes a memory leak, aka CID-9453264ef586.
CVE-2020-13800 3 Canonical, Opensuse, Qemu 3 Ubuntu Linux, Leap, Qemu 2022-04-28 4.9 MEDIUM 6.0 MEDIUM
ati-vga in hw/display/ati.c in QEMU 4.2.0 allows guest OS users to trigger infinite recursion via a crafted mm_index value during an ati_mm_read or ati_mm_write call.
CVE-2020-14641 3 Canonical, Netapp, Oracle 3 Ubuntu Linux, Snapcenter, Mysql 2022-04-28 4.0 MEDIUM 4.9 MEDIUM
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Security: Roles). Supported versions that are affected are 8.0.20 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Server accessible data. CVSS 3.1 Base Score 4.9 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N).

CVE-2020-12768 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2022-04-27 2.1 LOW 5.5 MEDIUM
** DISPUTED ** An issue was discovered in the Linux kernel before 5.6. svm_cpu_uninit in arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e. NOTE: third parties dispute this issue because it's a one-time leak at the boot, the size is negligible, and it can't be triggered at will.
CVE-2020-15780 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2022-04-27 7.2 HIGH 6.7 MEDIUM
An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot restrictions, aka CID-75b0cea7bf30.
CVE-2020-8992 4 Canonical, Linux, Netapp and 1 more 11 Ubuntu Linux, Linux Kernel, Active Iq Unified Manager and 8 more 2022-04-27 4.9 MEDIUM 5.5 MEDIUM

Mutt before 1.14.3 allows an IMAP fcc/postpone man-in-the-middle attack via a PREAUTH response.
CVE-2020-10029 5 Canonical, Fedoraproject, Gnu and 2 more 11 Ubuntu Linux, Fedora, Glibc and 8 more 2022-04-27 2.1 LOW 5.5 MEDIUM
The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c.
CVE-2020-11521 4 Canonical, Debian, Freerdp and 1 more 4 Ubuntu Linux, Debian Linux, Freerdp and 1 more 2022-04-26 6.0 MEDIUM 6.6 MEDIUM
libfreerdp/codec/planar.c in FreeRDP version > 1.0 through 2.0.0-rc4 has an Out-of-bounds Write.
CVE-2019-12529 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2022-04-26 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages.
CVE-2020-12392 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2022-04-26 2.1 LOW 5.5 MEDIUM
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in the disclosure of local files. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
CVE-2020-12771 6 Canonical, Debian, Linux and 3 more 37 Ubuntu Linux, Debian Linux, Linux Kernel and 34 more 2022-04-26 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in the Linux kernel through 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c has a deadlock if a coalescing operation fails.
CVE-2020-11765 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipad Os, Iphone Os and 9 more 2022-04-26 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. There is an off-by-one error in use of the ImfXdr.h read function by DwaCompressor::Classifier::Classifier, leading to an out-of-bounds read.
CVE-2020-11758 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipad Os, Iphone Os and 9 more 2022-04-26 4.3 MEDIUM 5.5 MEDIUM

In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server.
CVE-2021-3155 1 Canonical 2 Snapd, Ubuntu Linux 2022-02-25 2.1 LOW 5.5 MEDIUM
snapd 2.54.2 and earlier created ~/snap directories in user home directories without specifying owner-only permissions. This could allow a local attacker to read information that should have been private. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1
CVE-2016-2124 5 Canonical, Debian, Fedoraproject and 2 more 24 Ubuntu Linux, Debian Linux, Fedora and 21 more 2022-02-25 4.3 MEDIUM 5.9 MEDIUM
A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
CVE-2018-16845 5 Apple, Canonical, Debian and 2 more 5 Xcode, Ubuntu Linux, Debian Linux and 2 more 2022-02-22 5.8 MEDIUM 6.1 MEDIUM
nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.
CVE-2019-9516 11 Apache, Apple, Canonical and 8 more 20 Traffic Server, Mac Os X, Swiftnio and 17 more 2022-02-22 6.8 MEDIUM 6.5 MEDIUM
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.
CVE-2019-20807 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2022-02-21 4.6 MEDIUM 5.3 MEDIUM

CVE-2019-6454 8 Canonical, Debian, Fedoraproject and 5 more 22 Ubuntu Linux, Debian Linux, Fedora and 19 more 2022-02-20 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).
CVE-2017-16611 3 Canonical, Debian, X 3 Ubuntu Linux, Debian Linux, Libxfont 2022-02-20 4.9 MEDIUM 5.5 MEDIUM
In libXfont before 1.5.4 and libXfont2 before 2.0.3, a local attacker can open (but not read) files on the system as root, triggering tape rewinds, watchdogs, or similar mechanisms that can be triggered by opening files.
CVE-2017-17087 3 Canonical, Debian, Vim 3 Ubuntu Linux, Debian Linux, Vim 2022-02-20 2.1 LOW 5.5 MEDIUM
fileio.c in Vim prior to 8.0.1263 sets the group ownership of a .swp file to the editor's primary group (which may be different from the group ownership of the original file), which allows local users to obtain sensitive information by leveraging an applicable group membership, as demonstrated by /etc/shadow owned by root:shadow mode 0640, but /etc/.shadow.swp owned by root:users mode 0640, a different vulnerability than CVE-2017-1000382.
CVE-2017-17788 3 Canonical, Debian, Gimp 3 Ubuntu Linux, Debian Linux, Gimp 2022-02-07 4.3 MEDIUM 5.5 MEDIUM
In GIMP 2.8.22, there is a stack-based buffer over-read in xcf_load_stream in app/xcf/xcf.c when there is no '\0' character after the version string.
CVE-2020-1945 5 Apache, Canonical, Fedoraproject and 2 more 50 Ant, Ubuntu Linux, Fedora and 47 more 2022-02-07 3.3 LOW 6.3 MEDIUM
Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process.
CVE-2015-7977 8 Canonical, Debian, Fedoraproject and 5 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2022-02-01 4.3 MEDIUM 5.9 MEDIUM

CVE-2016-2383 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2022-01-31 2.1 LOW 5.5 MEDIUM
The adjust_branches function in kernel/bpf/verifier.c in the Linux kernel before 4.5 does not consider the delta in the backward-jump case, which allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions.
CVE-2018-16888 4 Canonical, Netapp, Redhat and 1 more 5 Ubuntu Linux, Active Iq Performance Analytics Services, Element Software and 2 more 2022-01-31 1.9 LOW 4.7 MEDIUM
It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.
CVE-2018-1049 4 Canonical, Debian, Redhat and 1 more 11 Ubuntu Linux, Debian Linux, Enterprise Linux and 8 more 2022-01-31 4.3 MEDIUM 5.9 MEDIUM
In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted.
CVE-2022-0319 2 Canonical, Vim 2 Ubuntu Linux, Vim 2022-01-27 4.3 MEDIUM 5.5 MEDIUM
Out-of-bounds Read in vim/vim prior to 8.2.

CVE-2019-16167 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2022-01-01 4.3 MEDIUM 5.5 MEDIUM
sysstat before 12.1.6 has memory corruption due to an Integer Overflow in remap_struct() in sa_common.c.
CVE-2020-8632 3 Canonical, Debian, Opensuse 3 Cloud-init, Debian Linux, Leap 2022-01-01 2.1 LOW 5.5 MEDIUM
In cloud-init through 19.4, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords.
CVE-2020-1700 4 Canonical, Ceph, Opensuse and 1 more 4 Ubuntu Linux, Ceph, Leap and 1 more 2022-01-01 6.8 MEDIUM 6.5 MEDIUM
A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects. An authenticated attacker can abuse this flaw by making multiple disconnect attempts resulting in a permanent leak of a socket connection by radosgw. This flaw could lead to a denial of service condition by pile up of CLOSE_WAIT sockets, eventually leading to the exhaustion of available resources, preventing legitimate users from connecting to the system.
CVE-2020-6792 2 Canonical, Mozilla 2 Ubuntu Linux, Thunderbird 2022-01-01 4.3 MEDIUM 4.3 MEDIUM
When deriving an identifier for an email message, uninitialized memory was used in addition to the message contents. This vulnerability affects Thunderbird < 68.5.
CVE-2020-6794 2 Canonical, Mozilla 2 Ubuntu Linux, Thunderbird 2022-01-01 4.3 MEDIUM 6.5 MEDIUM
If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Thunderbird 60. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Thunderbird < 68.5.
