CVE-2020-14362 3 Canonical, Redhat, X.org 3 Ubuntu Linux, Enterprise Linux, X Server 2025-08-29 4.6 MEDIUM 7.8 HIGH
A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-14361 3 Canonical, Redhat, X.org 3 Ubuntu Linux, Enterprise Linux, X Server 2025-08-29 4.6 MEDIUM 7.8 HIGH
A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-14346 3 Canonical, Redhat, X.org 3 Ubuntu Linux, Enterprise Linux, X Server 2025-08-29 4.6 MEDIUM 7.8 HIGH
A flaw was found in xorg-x11-server before 1.20.9. An integer underflow in the X input extension protocol decoding in the X server may lead to arbitrary access of memory contents. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-14347 3 Canonical, Debian, X.org 3 Ubuntu Linux, Debian Linux, X Server 2025-08-29 2.1 LOW 5.5 MEDIUM
A flaw was found in the way xserver memory was not properly initialized. This could leak parts of server memory to the X client. In cases where Xorg server runs with elevated privileges, this could result in possible ASLR bypass. Xorg-server before version 1.20.9 is vulnerable.
CVE-2022-1736 2 Canonical, Gnome 2 Ubuntu Linux, Gnome-remote-desktop 2025-08-26 N/A 9.8 CRITICAL
Ubuntu's configuration of gnome-control-center allowed Remote Desktop Sharing to be enabled by default.
CVE-2024-11586 2 Canonical, Pulseaudio 2 Ubuntu Linux, Pulseaudio 2025-08-26 N/A 4.0 MEDIUM
Ubuntu's implementation of pulseaudio can be crashed by a malicious program if a bluetooth headset is connected.
CVE-2021-3899 1 Canonical 2 Apport, Ubuntu Linux 2025-08-26 N/A 7.8 HIGH
There is a race condition in the 'replaced executable' detection that, with the correct local configuration, allow an attacker to execute arbitrary code as root.
CVE-2020-27352 1 Canonical 2 Snapd, Ubuntu Linux 2025-08-26 N/A 9.3 CRITICAL
When generating the systemd service units for the docker snap (and other similar snaps), snapd does not specify Delegate=yes - as a result systemd will move processes from the containers created and managed by these snaps into the cgroup of the main daemon within the snap itself when reloading system units. This may grant additional privileges to a container within the snap that were not originally intended.
CVE-2022-1804 1 Canonical 2 Accountsservice, Ubuntu Linux 2025-08-26 N/A 5.5 MEDIUM
accountsservice no longer drops permissions when writting .pam_environment
CVE-2023-5616 2 Canonical, Gnome 2 Ubuntu Linux, Control Center 2025-08-26 N/A 4.9 MEDIUM
In Ubuntu, gnome-control-center did not properly reflect SSH remote login status when the system was configured to use systemd socket activation for openssh-server. This could unknowingly leave the local machine exposed to remote SSH access contrary to expectation of the user.
CVE-2022-1242 1 Canonical 2 Apport, Ubuntu Linux 2025-08-22 N/A 7.8 HIGH
Apport can be tricked into connecting to arbitrary sockets as the root user
CVE-2015-7747 3 Audiofile, Canonical, Fedoraproject 3 Audiofile, Ubuntu Linux, Fedora 2025-08-13 6.8 MEDIUM 8.8 HIGH
Buffer overflow in the afReadFrames function in audiofile (aka libaudiofile and Audio File Library) allows user-assisted remote attackers to cause a denial of service (program crash) or possibly execute arbitrary code via a crafted audio file, as demonstrated by sixteen-stereo-to-eight-mono.c.
CVE-2018-17095 2 Audiofile, Canonical 2 Audiofile, Ubuntu Linux 2025-08-13 6.8 MEDIUM 8.8 HIGH
An issue has been discovered in mpruett Audio File Library (aka audiofile) 0.3.6, 0.3.5, 0.3.4, 0.3.3, 0.3.2, 0.3.1, 0.3.0. A heap-based buffer overflow in Expand3To4Module::run has occurred when running sfconvert.
CVE-2018-13440 2 Audiofile, Canonical 2 Audiofile, Ubuntu Linux 2025-08-13 4.3 MEDIUM 6.5 MEDIUM
The audiofile Audio File Library 0.3.6 has a NULL pointer dereference bug in ModuleState::setup in modules/ModuleState.cpp, which allows an attacker to cause a denial of service via a crafted caf file, as demonstrated by sfconvert.
CVE-2019-13454 4 Canonical, Debian, Imagemagick and 1 more 4 Ubuntu Linux, Debian Linux, Imagemagick and 1 more 2025-07-11 4.3 MEDIUM 6.5 MEDIUM
