CVE-2020-14346 3 Canonical, Redhat, X.org 3 Ubuntu Linux, Enterprise Linux, X Server 2025-08-29 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 4 Canonical, Debian, Redhat and 1 more 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more 2025-08-29 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-2020-14361 3 Canonical, Redhat, X.org 3 Ubuntu Linux, Enterprise Linux, X Server 2025-08-29 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-2018-14665 4 Canonical, Debian, Redhat and 1 more 10 Ubuntu Linux, Debian Linux, Enterprise Linux and 7 more 2025-08-29 N/A
A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges.
CVE-2020-14362 3 Canonical, Redhat, X.org 3 Ubuntu Linux, Enterprise Linux, X Server 2025-08-29 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-2022-1736 2 Canonical, Gnome 2 Ubuntu Linux, Gnome-remote-desktop 2025-08-26 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 4 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 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 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 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 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-2008-0888 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2025-08-26 N/A
The NEEDBITS macro in the inflate_dynamic function in inflate.c for unzip can be invoked using invalid buffers, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors that trigger a free of uninitialized or previously-freed data.
CVE-2025-5054 1 Canonical 2 Apport, Ubuntu Linux 2025-08-22 4.7 Medium
Race condition in Canonical apport up to and including 2.32.0 allows a local attacker to leak sensitive information via PID-reuse by leveraging namespaces. When handling a crash, the function `_check_global_pid_and_forward`, which detects if the crashing process resided in a container, was being called before `consistency_checks`, which attempts to detect if the crashing process had been replaced. Because of this, if a process crashed and was quickly replaced with a containerized one, apport could be made to forward the core dump to the container, potentially leaking sensitive information. `consistency_checks` is now being called before `_check_global_pid_and_forward`. Additionally, given that the PID-reuse race condition cannot be reliably detected from userspace alone, crashes are only forwarded to containers if the kernel provided a pidfd, or if the crashing process was unprivileged (i.e., if dump mode == 1).
CVE-2022-1242 1 Canonical 2 Apport, Ubuntu Linux 2025-08-22 7.8 High
Apport can be tricked into connecting to arbitrary sockets as the root user
CVE-2023-4911 6 Canonical, Debian, Fedoraproject and 3 more 40 Ubuntu Linux, Debian Linux, Fedora and 37 more 2025-08-21 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-2018-13440 3 Audiofile, Canonical, Redhat 3 Audiofile, Ubuntu Linux, Enterprise Linux 2025-08-13 N/A
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-2018-17095 3 Audiofile, Canonical, Redhat 3 Audiofile, Ubuntu Linux, Enterprise Linux 2025-08-13 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-2015-7747 3 Audiofile, Canonical, Fedoraproject 3 Audiofile, Ubuntu Linux, Fedora 2025-08-13 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-2015-4495 6 Canonical, Mozilla, Opensuse and 3 more 16 Ubuntu Linux, Firefox, Firefox Os and 13 more 2025-07-30 8.8 High
The PDF reader in Mozilla Firefox before 39.0.3, Firefox ESR 38.x before 38.1.1, and Firefox OS before 2.2 allows remote attackers to bypass the Same Origin Policy, and read arbitrary files or gain privileges, via vectors involving crafted JavaScript code and a native setter, as exploited in the wild in August 2015.
CVE-2010-0840 4 Canonical, Opensuse, Oracle and 1 more 7 Ubuntu Linux, Opensuse, Jre and 4 more 2025-07-30 9.8 Critical
Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE and Java for Business 6 Update 18, 5.0 Update 23, and 1.4.2_25 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the March 2010 CPU. Oracle has not commented on claims from a reliable researcher that this is related to improper checks when executing privileged methods in the Java Runtime Environment (JRE), which allows attackers to execute arbitrary code via (1) an untrusted object that extends the trusted class but has not modified a certain method, or (2) "a similar trust issue with interfaces," aka "Trusted Methods Chaining Remote Code Execution Vulnerability."
