CVE-2020-13777 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2020-06-19 5.8 MEDIUM 7.4 HIGH
GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application.
CVE-2016-7426 4 Canonical, Hpe, Ntp and 1 more 9 Ubuntu Linux, Hpux-ntp, Ntp and 6 more 2020-06-18 4.3 MEDIUM 7.5 HIGH
NTP before 4.2.8p9 rate limits responses received from the configured sources when rate limiting for all associations is enabled, which allows remote attackers to cause a denial of service (prevent responses from the sources) by sending responses with a spoofed source address.
CVE-2018-1000888 3 Canonical, Debian, Php 3 Ubuntu Linux, Debian Linux, Pear Archive Tar 2020-06-15 6.8 MEDIUM 8.8 HIGH
PEAR Archive_Tar version 1.4.3 and earlier contains a CWE-502, CWE-915 vulnerability in the Archive_Tar class. There are several file operations with `$v_header['filename']` as parameter (such as file_exists, is_file, is_dir, etc). When extract is called without a specific prefix path, we can trigger unserialization by crafting a tar file with `phar://[path_to_malicious_phar_file]` as path. Object injection can be used to trigger destruct in the loaded PHP classes, e.g. the Archive_Tar class itself. With Archive_Tar object injection, arbitrary file deletion can occur because `@unlink($this->_temp_tarname)` is called. If another class with useful gadget is loaded, it may possible to cause remote code execution that can result in files being deleted or possibly modified. This vulnerability appears to have been fixed in 1.4.4.
CVE-2020-11793 5 Canonical, Fedoraproject, Opensuse and 2 more 5 Ubuntu Linux, Fedora, Leap and 2 more 2020-06-13 6.8 MEDIUM 8.8 HIGH
A use-after-free issue exists in WebKitGTK before 2.28.1 and WPE WebKit before 2.28.1 via crafted web content that allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash).
CVE-2019-11596 2 Canonical, Memcached 2 Ubuntu Linux, Memcached 2020-05-26 5.0 MEDIUM 7.5 HIGH
In memcached before 1.5.14, a NULL pointer dereference was found in the "lru mode" and "lru temp_ttl" commands. This causes a denial of service when parsing crafted lru command messages in process_lru_command in memcached.c.
CVE-2020-11008 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2020-05-22 5.0 MEDIUM 7.5 HIGH
Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials to a host controlled by an attacker. This bug is similar to CVE-2020-5260(GHSA-qm7j-c969-7j4q). The fix for that bug still left the door open for an exploit where _some_ credential is leaked (but the attacker cannot control which one). Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that are considered illegal as of the recently published Git versions can cause Git to send a "blank" pattern to helpers, missing hostname and protocol fields. Many helpers will interpret this as matching _any_ URL, and will return some unspecified stored password, leaking the password to an attacker's server. The vulnerability can be triggered by feeding a malicious URL to `git clone`. However, the affected URLs look rather suspicious; the likely vector would be through systems which automatically clone URLs not visible to the user, such as Git submodules, or package systems built around Git. The root of the problem is in Git itself, which should not be feeding blank input to helpers. However, the ability to exploit the vulnerability in practice depends on which helpers are in use. Credential helpers which are known to trigger the vulnerability: - Git's "store" helper - Git's "cache" helper - the "osxkeychain" helper that ships in Git's "contrib" directory Credential helpers which are known to be safe even with vulnerable versions of Git: - Git Credential Manager for Windows Any helper not in this list should be assumed to trigger the vulnerability.
CVE-2018-16867 3 Canonical, Fedoraproject, Qemu 3 Ubuntu Linux, Fedora, Qemu 2020-05-14 4.4 MEDIUM 7.8 HIGH
A flaw was found in qemu Media Transfer Protocol (MTP) before version 3.1.0. A path traversal in the in usb_mtp_write_data function in hw/usb/dev-mtp.c due to an improper filename sanitization. When the guest device is mounted in read-write mode, this allows to read/write arbitrary files which may lead do DoS scenario OR possibly lead to code execution on the host.
CVE-2018-16847 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2020-05-14 4.6 MEDIUM 7.8 HIGH
An OOB heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It could occur in nvme_cmb_ops routines in nvme device.

CVE-2018-7550 4 Canonical, Debian, Qemu and 1 more 9 Ubuntu Linux, Debian Linux, Qemu and 6 more 2020-05-14 4.6 MEDIUM 8.8 HIGH
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.
CVE-2018-20191 3 Canonical, Fedoraproject, Qemu 3 Ubuntu Linux, Fedora, Qemu 2020-05-12 5.0 MEDIUM 7.5 HIGH
hw/rdma/vmw/pvrdma_main.c in QEMU does not implement a read operation (such as uar_read by analogy to uar_write), which allows attackers to cause a denial of service (NULL pointer dereference).
CVE-2018-20125 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2020-05-12 5.0 MEDIUM 7.5 HIGH
hw/rdma/vmw/pvrdma_cmd.c in QEMU allows attackers to cause a denial of service (NULL pointer dereference or excessive memory allocation) in create_cq_ring or create_qp_rings.
CVE-2018-20216 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2020-05-12 5.0 MEDIUM 7.5 HIGH
QEMU can have an infinite loop in hw/rdma/vmw/pvrdma_dev_ring.c because return values are not checked (and -1 is mishandled).
CVE-2016-5421 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2020-05-08 6.8 MEDIUM 8.1 HIGH
Use-after-free vulnerability in libcurl before 7.50.1 allows attackers to control which connection is used or possibly have unspecified other impact via unknown vectors.
CVE-2018-11235 5 Canonical, Debian, Git-scm and 2 more 9 Ubuntu Linux, Debian Linux, Git and 6 more 2020-05-02 6.8 MEDIUM 7.8 HIGH
In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with "../" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.
CVE-2018-11233 2 Canonical, Git-scm 2 Ubuntu Linux, Git 2020-05-02 5.0 MEDIUM 7.5 HIGH
In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, code to sanity-check pathnames on NTFS can result in reading out-of-bounds memory.
CVE-2019-15791 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-05-01 4.6 MEDIUM 7.8 HIGH
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, which then puts a reference to that file, leading to a refcount underflow.
CVE-2019-15792 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-05-01 4.6 MEDIUM 7.8 HIGH
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() calls fdget(oldfd), then without further checks passes the resulting file* into shiftfs_real_fdget(), which casts file->private_data, a void* that points to a filesystem-dependent type, to a "struct shiftfs_file_info *". As the private_data is not required to be a pointer, an attacker can use this to cause a denial of service or possibly execute arbitrary code.
CVE-2019-15793 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-05-01 4.6 MEDIUM 8.8 HIGH
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, several locations which shift ids translate user/group ids before performing operations in the lower filesystem were translating them into init_user_ns, whereas they should have been translated into the s_user_ns for the lower filesystem. This resulted in using ids other than the intended ones in the lower fs, which likely did not map into the shifts s_user_ns. A local attacker could use this to possibly bypass discretionary access control permissions.
CVE-2019-11480 1 Canonical 1 C-kernel 2020-04-14 6.8 MEDIUM 8.1 HIGH
The pc-kernel snap build process hardcoded the --allow-insecure-repositories and --allow-unauthenticated apt options when creating the build chroot environment. This could allow an attacker who is able to perform a MITM attack between the build environment and the Ubuntu archive to install a malicious package within the build chroot. This issue affects pc-kernel versions prior to and including 2019-07-16
CVE-2018-1000222 3 Canonical, Debian, Libgd 3 Ubuntu Linux, Debian Linux, Libgd 2020-03-31 6.8 MEDIUM 8.8 HIGH
