CVE-2019-17026 2 Canonical, Mozilla 3 Ubuntu Linux, Firefox, Thunderbird 2025-03-21 6.8 MEDIUM 8.8 HIGH
Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Firefox ESR < 68.4.1, Thunderbird < 68.4.1, and Firefox < 72.0.1.
CVE-2023-3777 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-03-20 N/A 7.8 HIGH
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8.

CVE-2020-16297 3 Artifex, Canonical, Debian 3 Ghostscript, Ubuntu Linux, Debian Linux 2025-03-14 4.3 MEDIUM 5.5 MEDIUM
A buffer overflow vulnerability in FloydSteinbergDitheringC() in contrib/gdevbjca.c of Artifex Software GhostScript v9.18 to v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.
CVE-2022-28652 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2025-03-13 N/A 5.5 MEDIUM
~/.config/apport/settings parsing is vulnerable to "billion laughs" attack
CVE-2019-16928 4 Canonical, Debian, Exim and 1 more 4 Ubuntu Linux, Debian Linux, Exim and 1 more 2025-03-07 7.5 HIGH 9.8 CRITICAL
Exim 4.92 through 4.92.2 allows remote code execution, a different vulnerability than CVE-2019-15846. There is a heap-based buffer overflow in string_vformat in string.c involving a long EHLO command.
CVE-2020-16291 3 Artifex, Canonical, Debian 3 Ghostscript, Ubuntu Linux, Debian Linux 2025-03-04 4.3 MEDIUM 5.5 MEDIUM
A buffer overflow vulnerability in contrib/gdevdj9.c of Artifex Software GhostScript v9.18 to v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.
CVE-2019-13454 4 Canonical, Debian, Imagemagick and 1 more 4 Ubuntu Linux, Debian Linux, Imagemagick and 1 more 2025-03-04 4.3 MEDIUM 6.5 MEDIUM
ImageMagick 7.0.1-0 to 7.0.8-54 Q16 allows Division by Zero in RemoveDuplicateLayers in MagickCore/layer.c.
CVE-2022-2586 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2025-02-19 N/A 5.3 MEDIUM
It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted.
CVE-2021-3493 1 Canonical 1 Ubuntu Linux 2025-02-19 7.2 HIGH 8.8 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-2019-11043 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2025-02-14 7.5 HIGH 8.7 HIGH
In PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24 and 7.3.x below 7.3.11 in certain configurations of FPM setup it is possible to cause FPM module to write past allocated buffers into the space reserved for FCGI protocol data, thus opening the possibility of remote code execution.
CVE-2023-3389 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-02-13 N/A 7.8 HIGH
A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and 0e388fce7aec40992eadee654193cad345d62663 for 5.15 stable).

An issue was discovered in Qt before 5.11.3. QBmpHandler has a buffer overflow via BMP data.
CVE-2022-2084 1 Canonical 2 Cloud-init, Ubuntu Linux 2025-02-05 N/A 5.5 MEDIUM
Sensitive data could be exposed in world readable logs of cloud-init before version 22.3 when schema failures are reported. This leak could include hashed passwords.
CVE-2021-3429 1 Canonical 1 Cloud-init 2025-02-05 N/A 5.5 MEDIUM
When instructing cloud-init to set a random password for a new user account, versions before 21.2 would write that password to the world-readable log file /var/log/cloud-init-output.log. This could allow a local user to log in as another user.
CVE-2023-4911 6 Canonical, Debian, Fedoraproject and 3 more 38 Ubuntu Linux, Debian Linux, Fedora and 35 more 2025-01-27 N/A 7.8 HIGH
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2019-19344 4 Canonical, Opensuse, Samba and 1 more 7 Ubuntu Linux, Leap, Samba and 4 more 2025-01-14 4.0 MEDIUM 6.5 MEDIUM
