Local attackers with a X connection able to provide PCX fonts to the X server xorg-server before 21.2.24 and xwayland before 24.1.13 could cause a heap buffer overflow via SetFont due to missing glyph boundary checks.
CVE-2022-46340 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2026-06-17 8.8 High
A vulnerability was found in X.Org. This security flaw occurs becuase the swap handler for the XTestFakeInput request of the XTest extension may corrupt the stack if GenericEvents with lengths larger than 32 bytes are sent through a the XTestFakeInput request. 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. This issue does not affect systems where client and server use the same byte order.
CVE-2022-3551 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2026-06-17 3.5 Low
A vulnerability, which was classified as problematic, has been found in X.org Server. Affected by this issue is the function ProcXkbGetKbdByName of the file xkb/xkb.c. The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211052.
CVE-2022-3550 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2026-06-17 5.5 Medium
A vulnerability classified as critical was found in X.org Server. Affected by this vulnerability is the function _GetCountedString of the file xkb/xkb.c. The manipulation leads to buffer overflow. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211051.
CVE-2007-6429 2 Redhat, X.org 4 Enterprise Linux, Evi, Mit-shm and 1 more 2026-04-23 N/A
Multiple integer overflows in X.Org Xserver before 1.4.1 allow context-dependent attackers to execute arbitrary code via (1) a GetVisualInfo request containing a 32-bit value that is improperly used to calculate an amount of memory for allocation by the EVI extension, or (2) a request containing values related to pixmap size that are improperly used in management of shared memory by the MIT-SHM extension.
CVE-2006-5397 1 X.org 1 Libx11 2026-04-23 N/A
The Xinput module (modules/im/ximcp/imLcIm.c) in X.Org libX11 1.0.2 and 1.0.3 opens a file for reading twice using the same file descriptor, which causes a file descriptor leak that allows local users to read files specified by the XCOMPOSEFILE environment variable via the duplicate file descriptor.
CVE-2007-6428 2 Redhat, X.org 3 Enterprise Linux, Tog-cup, Xserver 2026-04-23 N/A
The ProcGetReservedColormapEntries function in the TOG-CUP extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to read the contents of arbitrary memory locations via a request containing a 32-bit value that is improperly used as an array index.
CVE-2007-6427 8 Apple, Canonical, Debian and 5 more 12 Mac Os X, Ubuntu Linux, Debian Linux and 9 more 2026-04-23 N/A
The XInput extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via requests related to byte swapping and heap corruption within multiple functions, a different vulnerability than CVE-2007-4990.
CVE-2006-5215 3 Netbsd, Sun, X.org 4 Netbsd, Solaris, Sunos and 1 more 2026-04-23 N/A
The Xsession script, as used by X Display Manager (xdm) in NetBSD before 20060212, X.Org before 20060317, and Solaris 8 through 10 before 20061006, allows local users to overwrite arbitrary files, or read another user's Xsession errors file, via a symlink attack on a /tmp/xses-$USER file.
CVE-2007-5958 2 Redhat, X.org 2 Enterprise Linux, Xserver 2026-04-23 N/A
X.Org Xserver before 1.4.1 allows local users to determine the existence of arbitrary files via a filename argument in the -sp option to the X program, which produces different error messages depending on whether the filename exists.
CVE-2007-5760 3 Redhat, X.org, Xfree86 Project 3 Enterprise Linux, Xserver, Xfree86-misc 2026-04-23 N/A
Array index error in the XFree86-Misc extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via a PassMessage request containing a large array index.
