xorg-x11-server before 1.19.5 was vulnerable to integer overflow in (S)ProcXIBarrierReleasePointer functions allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12181 2 Debian, X.org 2 Debian Linux, X Server 2025-08-29 N/A
xorg-x11-server before 1.19.5 was missing length validation in XFree86 DGA extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12187 2 Debian, X.org 2 Debian Linux, X Server 2025-08-29 N/A
xorg-x11-server before 1.19.5 was missing length validation in RENDER extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-13723 2 Debian, X.org 2 Debian Linux, X Server 2025-08-29 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 X Server 2025-08-29 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-2017-2624 2 Debian, X.org 2 Debian Linux, X Server 2025-08-29 N/A
It was found that xorg-x11-server before 1.19.0 including uses memcmp() to check the received MIT cookie against a series of valid cookies. If the cookie is correct, it is allowed to attach to the Xorg session. Since most memcmp() implementations return after an invalid byte is seen, this causes a time difference between a valid and invalid byte, which could allow an efficient brute force attack.
CVE-2017-12185 2 Debian, X.org 2 Debian Linux, X Server 2025-08-29 N/A
xorg-x11-server before 1.19.5 was missing length validation in MIT-SCREEN-SAVER extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2017-12180 2 Debian, X.org 2 Debian Linux, X Server 2025-08-29 N/A
xorg-x11-server before 1.19.5 was missing length validation in XFree86 VidModeExtension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.
CVE-2015-0255 3 Opensuse, Redhat, X.org 3 Opensuse, Enterprise Linux, X Server 2025-08-29 N/A
X.Org Server (aka xserver and xorg-server) before 1.16.3 and 1.17.x before 1.17.1 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (crash) via a crafted string length value in a XkbSetGeometry request.
CVE-2022-2320 2 Redhat, X.org 2 Enterprise Linux, X Server 2025-08-29 7.8 High
A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to escalate privileges and execute arbitrary code in the context of root.
CVE-2022-4283 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-08-29 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-2022-46343 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 because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. 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-2022-46342 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 because the handler for the XvdiSelectVideoNotify request may write to memory after it has been freed. This issue can lead to local privileges elevation on systems where the X se
CVE-2022-46341 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 because the handler for the XIPassiveUngrab request accesses out-of-bounds memory when invoked with a high keycode or button code. 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-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-2017-13722 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-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-2016-7944 2 Fedoraproject, X.org 2 Fedora, Libxfixes 2025-04-12 N/A
Integer overflow in X.org libXfixes before 5.0.3 on 32-bit platforms might allow remote X servers to gain privileges via a length value of INT_MAX, which triggers the client to stop reading data and get out of sync.
CVE-2016-7952 2 Fedoraproject, X.org 2 Fedora, Libxtst 2025-04-12 N/A
X.org libXtst before 1.2.3 allows remote X servers to cause a denial of service (infinite loop) via a reply in the (1) XRecordStartOfData, (2) XRecordEndOfData, or (3) XRecordClientDied category without a client sequence and with attached data.
