CVE-2022-46340 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-22 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-2017-13720 1 X.org 1 Libxfont 2025-04-20 N/A
In the PatternMatch function in fontfile/fontdir.c in libXfont through 1.5.2 and 2.x before 2.0.2, an attacker with access to an X connection can cause a buffer over-read during pattern matching of fonts, leading to information disclosure or a crash (denial of service). This occurs because '\0' characters are incorrectly skipped in situations involving ? characters.
CVE-2016-10164 2 Redhat, X.org 2 Enterprise Linux, Libxpm 2025-04-20 N/A
Multiple integer overflows in libXpm before 3.5.12, when a program requests parsing XPM extensions on a 64-bit platform, allow remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via (1) the number of extensions or (2) their concatenated length in a crafted XPM file, which triggers a heap-based buffer overflow.
CVE-2017-13721 2 Debian, X.org 2 Debian Linux, Xorg-server 2025-04-20 N/A
In X.Org Server (aka xserver and xorg-server) before 1.19.4, an attacker authenticated to an X server with the X shared memory extension enabled can cause aborts of the X server or replace shared memory segments of other X clients in the same session.
CVE-2017-13722 1 X.org 1 Libxfont 2025-04-20 N/A
In the pcfGetProperties function in bitmap/pcfread.c in libXfont through 1.5.2 and 2.x before 2.0.2, a missing boundary check (for PCF files) could be used by local attackers authenticated to an Xserver for a buffer over-read, for information disclosure or a crash of the X server.
CVE-2017-10971 1 X.org 1 Xorg-server 2025-04-20 N/A
In the X.Org X server before 2017-06-19, a user authenticated to an X Session could crash or execute code in the context of the X Server by exploiting a stack overflow in the endianness conversion of X Events.
CVE-2017-13723 2 Debian, X.org 2 Debian Linux, Xorg-server 2025-04-20 N/A
In X.Org Server (aka xserver and xorg-server) before 1.19.4, a local attacker authenticated to the X server could overflow a global buffer, causing crashes of the X server or potentially other problems by injecting large or malformed XKB related atoms and accessing them via xkbcomp.
CVE-2017-10972 1 X.org 1 Xorg-server 2025-04-20 N/A
Uninitialized data in endianness conversion in the XEvent handling of the X.Org X Server before 2017-06-19 allowed authenticated malicious users to access potentially privileged data from the X server.
CVE-2022-3550 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-15 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-2022-3551 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-15 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-2022-3553 1 X.org 1 X Server 2025-04-15 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.
CVE-2022-4283 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-14 7.8 High
A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. 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-2016-5407 2 Fedoraproject, X.org 2 Fedora, Libxv 2025-04-12 N/A
The (1) XvQueryAdaptors and (2) XvQueryEncodings functions in X.org libXv before 1.0.11 allow remote X servers to trigger out-of-bounds memory access operations via vectors involving length specifications in received data.
CVE-2015-3418 2 Redhat, X.org 2 Enterprise Linux, Xorg-server 2025-04-12 N/A
The ProcPutImage function in dix/dispatch.c in X.Org Server (aka xserver and xorg-server) before 1.16.4 allows attackers to cause a denial of service (divide-by-zero and crash) via a zero-height PutImage request.
CVE-2016-7947 2 Fedoraproject, X.org 2 Fedora, Libxrandr 2025-04-12 N/A
