A vulnerability in the Data-Loss-Prevention (DLP) module in Clam AntiVirus (ClamAV) Software versions 0.102.1 and 0.102.0 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to an out-of-bounds read affecting users that have enabled the optional DLP feature. An attacker could exploit this vulnerability by sending a crafted email file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition.
CVE-2015-0258 3 Canonical, Debian, O-dyn 3 Ubuntu Linux, Debian Linux, Collabtive 2022-01-01 6.5 MEDIUM 8.8 HIGH
Multiple incomplete blacklist vulnerabilities in the avatar upload functionality in manageuser.php in Collabtive before 2.1 allow remote authenticated users to execute arbitrary code by uploading a file with a (1) .php3, (2) .php4, (3) .php5, or (4) .phtml extension.
CVE-2020-9308 3 Canonical, Fedoraproject, Libarchive 3 Ubuntu Linux, Fedora, Libarchive 2022-01-01 6.8 MEDIUM 8.8 HIGH
archive_read_support_format_rar5.c in libarchive before 3.4.2 attempts to unpack a RAR5 file with an invalid or corrupted header (such as a header size of zero), leading to a SIGSEGV or possibly unspecified other impact.
CVE-2020-10174 3 Canonical, Fedoraproject, Timeshift Project 3 Ubuntu Linux, Fedora, Timeshift 2022-01-01 6.9 MEDIUM 7.0 HIGH
init_tmp in TeeJee.FileSystem.vala in Timeshift before 20.03 unsafely reuses a preexisting temporary directory in the predictable location /tmp/timeshift. It follows symlinks in this location or uses directories owned by unprivileged users. Because Timeshift also executes scripts under this location, an attacker can attempt to win a race condition to replace scripts created by Timeshift with attacker-controlled scripts. Upon success, an attacker-controlled script is executed with full root privileges. This logic is practically always triggered when Timeshift runs regardless of the command-line arguments used.
CVE-2020-6800 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2022-01-01 6.8 MEDIUM 8.8 HIGH
Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.
CVE-2020-6801 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2022-01-01 6.8 MEDIUM 8.8 HIGH

CVE-2020-7062 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2022-01-01 4.3 MEDIUM 7.5 HIGH
In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when using file upload functionality, if upload progress tracking is enabled, but session.upload_progress.cleanup is set to 0 (disabled), and the file upload fails, the upload procedure would try to clean up data that does not exist and encounter null pointer dereference, which would likely lead to a crash.
CVE-2020-14382 4 Canonical, Cryptsetup Project, Fedoraproject and 1 more 4 Ubuntu Linux, Cryptsetup, Fedora and 1 more 2022-01-01 6.8 MEDIUM 7.8 HIGH
A vulnerability was found in upstream release cryptsetup-2.2.0 where, there's a bug in LUKS2 format validation code, that is effectively invoked on every device/image presenting itself as LUKS2 container. The bug is in segments validation code in file 'lib/luks2/luks2_json_metadata.c' in function hdr_validate_segments(struct crypt_device *cd, json_object *hdr_jobj) where the code does not check for possible overflow on memory allocation used for intervals array (see statement "intervals = malloc(first_backup * sizeof(*intervals));"). Due to the bug, library can be *tricked* to expect such allocation was successful but for far less memory then originally expected. Later it may read data FROM image crafted by an attacker and actually write such data BEYOND allocated memory.
CVE-2020-16119 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2022-01-01 4.6 MEDIUM 7.8 HIGH
Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196.

CVE-2019-6690 5 Canonical, Debian, Opensuse and 2 more 6 Ubuntu Linux, Debian Linux, Leap and 3 more 2021-12-28 5.0 MEDIUM 7.5 HIGH
python-gnupg 0.4.3 allows context-dependent attackers to trick gnupg to decrypt other ciphertext than intended. To perform the attack, the passphrase to gnupg must be controlled by the adversary and the ciphertext should be trusted. Related to a "CWE-20: Improper Input Validation" issue affecting the affect functionality component.
CVE-2018-1000805 4 Canonical, Debian, Paramiko and 1 more 11 Ubuntu Linux, Debian Linux, Paramiko and 8 more 2021-12-28 6.5 MEDIUM 8.8 HIGH
Paramiko version 2.4.1, 2.3.2, 2.2.3, 2.1.5, 2.0.8, 1.18.5, 1.17.6 contains a Incorrect Access Control vulnerability in SSH server that can result in RCE. This attack appear to be exploitable via network connectivity.
CVE-2018-5764 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Rsync 2021-12-16 5.0 MEDIUM 7.5 HIGH
The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple --protect-args uses, which allows remote attackers to bypass an argument-sanitization protection mechanism.
CVE-2021-3493 1 Canonical 1 Ubuntu Linux 2021-12-16 7.2 HIGH 7.8 HIGH
The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow unprivileged overlay mounts, an attacker could use this to gain elevated privileges.
CVE-2019-5736 13 Apache, Canonical, D2iq and 10 more 19 Mesos, Ubuntu Linux, Dc\/os and 16 more 2021-12-16 9.3 HIGH 8.6 HIGH
runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.
CVE-2016-0742 6 Apple, Canonical, Debian and 3 more 6 Xcode, Ubuntu Linux, Debian Linux and 3 more 2021-12-15 5.0 MEDIUM 7.5 HIGH

CVE-2019-13272 6 Canonical, Debian, Fedoraproject and 3 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2021-11-28 7.2 HIGH 7.8 HIGH
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.
CVE-2021-3939 1 Canonical 2 Accountsservice, Ubuntu Linux 2021-11-19 7.2 HIGH 7.8 HIGH
Ubuntu-specific modifications to accountsservice (in patch file debian/patches/0010-set-language.patch) caused the fallback_locale variable, pointing to static storage, to be freed, in the user_change_language_authorized_cb function. This is reachable via the SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5, 0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1.
