CVE-2006-0745 5 Mandrakesoft, Redhat, Sun and 2 more 6 Mandrake Linux, Fedora Core, Solaris and 3 more 2025-04-03 7.2 HIGH N/A
X.Org server (xorg-server) 1.0.0 and later, X11R6.9.0, and X11R7.0 inadvertently treats the address of the geteuid function as if it is the return value of a call to geteuid, which allows local users to bypass intended restrictions and (1) execute arbitrary code via the -modulepath command line option or (2) overwrite arbitrary files via -logfile.
CVE-2022-44617 1 X.org 1 Libxpm 2025-03-25 N/A 7.5 HIGH
A flaw was found in libXpm. When processing a file with width of 0 and a very large height, some parser functions will be called repeatedly and can lead to an infinite loop, resulting in a Denial of Service in the application linked to the library.
CVE-2022-46285 1 X.org 1 Libxpm 2025-03-25 N/A 7.5 HIGH
A flaw was found in libXpm. This issue occurs when parsing a file with a comment not closed; the end-of-file condition will not be detected, leading to an infinite loop and resulting in a Denial of Service in the application linked to the library.
CVE-2022-4883 1 X.org 1 Libxpm 2025-03-20 N/A 8.8 HIGH
A flaw was found in libXpm. When processing files with .Z or .gz extensions, the library calls external programs to compress and uncompress files, relying on the PATH environment variable to find these programs, which could allow a malicious user to execute other programs by manipulating the PATH environment variable.
CVE-2023-0494 3 Fedoraproject, Redhat, X.org 18 Fedora, Enterprise Linux, Enterprise Linux Aus and 15 more 2025-02-24 N/A 7.8 HIGH
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions.
CVE-2023-5574 2 Redhat, X.org 2 Enterprise Linux, X Server 2024-11-21 N/A 7.0 HIGH
A use-after-free flaw was found in xorg-x11-server-Xvfb. This issue occurs in Xvfb with a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode). If the pointer is warped from a screen 1 to a screen 0, a use-after-free issue may be triggered during shutdown or reset of the Xvfb server, allowing for possible escalation of privileges or denial of service.
CVE-2023-5380 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Enterprise Linux and 2 more 2024-11-21 N/A 4.7 MEDIUM
A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed.
CVE-2023-43788 3 Fedoraproject, Redhat, X.org 3 Fedora, Enterprise Linux, Libxpm 2024-11-21 N/A 5.5 MEDIUM
A vulnerability was found in libXpm due to a boundary condition within the XpmCreateXpmImageFromBuffer() function. This flaw allows a local attacker to trigger an out-of-bounds read error and read the contents of memory on the system.
CVE-2023-43787 3 Fedoraproject, Redhat, X.org 3 Fedora, Enterprise Linux, Libx11 2024-11-21 N/A 7.8 HIGH
A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges.
CVE-2023-43786 3 Fedoraproject, Redhat, X.org 3 Fedora, Enterprise Linux, Libx11 2024-11-21 N/A 5.5 MEDIUM
A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition.
CVE-2023-43785 3 Fedoraproject, Redhat, X.org 3 Fedora, Enterprise Linux, Libx11 2024-11-21 N/A 6.5 MEDIUM
A vulnerability was found in libX11 due to a boundary condition within the _XkbReadKeySyms() function. This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system.
CVE-2023-3138 2 Redhat, X.org 2 Enterprise Linux, Libx11 2024-11-21 N/A 7.5 HIGH
A vulnerability was found in libX11. The security flaw occurs because the functions in src/InitExt.c in libX11 do not check that the values provided for the Request, Event, or Error IDs are within the bounds of the arrays that those functions write to, using those IDs as array indexes. They trust that they were called with values provided by an Xserver adhering to the bounds specified in the X11 protocol, as all X servers provided by X.Org do. As the protocol only specifies a single byte for these values, an out-of-bounds value provided by a malicious server (or a malicious proxy-in-the-middle) can only overwrite other portions of the Display structure and not write outside the bounds of the Display structure itself, possibly causing the client to crash with this memory corruption.
CVE-2022-46344 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-11-21 N/A 8.8 HIGH
A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIChangeProperty request has a length-validation issues, resulting in out-of-bounds memory reads and potential information disclosure. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions.
CVE-2022-3553 1 X.org 1 X Server 2024-11-21 N/A 3.5 LOW
A vulnerability, which was classified as problematic, was found in X.org Server. This affects an unknown part of the file hw/xquartz/X11Controller.m of the component xquartz. The manipulation leads to denial of service. It is recommended to apply a patch to fix this issue. The identifier VDB-211053 was assigned to this vulnerability.
