CVE-2023-6377 4 Debian, Redhat, Tigervnc and 1 more 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more 2025-08-18 N/A 7.8 HIGH
A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.
CVE-2023-6478 4 Debian, Redhat, Tigervnc and 1 more 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more 2025-08-04 N/A 7.6 HIGH
A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information.
CVE-2022-46343 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-22 N/A 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 N/A 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 N/A 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-2022-46340 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-22 N/A 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 3.6 LOW 7.1 HIGH
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-2017-13722 1 X.org 1 Libxfont 2025-04-20 3.6 LOW 7.1 HIGH
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-2016-7948 2 Fedoraproject, X.org 2 Fedora, Libxrandr 2025-04-12 7.5 HIGH 9.8 CRITICAL
X.org libXrandr before 1.5.1 allows remote X servers to trigger out-of-bounds write operations by leveraging mishandling of reply data.
CVE-2013-7439 3 Canonical, Debian, X.org 4 Ubuntu Linux, Debian Linux, Libx11 and 1 more 2025-04-12 7.5 HIGH N/A
Multiple off-by-one errors in the (1) MakeBigReq and (2) SetReqLen macros in include/X11/Xlibint.h in X11R6.x and libX11 before 1.6.0 allow remote attackers to have unspecified impact via a crafted request, which triggers a buffer overflow.
CVE-2016-7953 2 Fedoraproject, X.org 2 Fedora, Libxvmc 2025-04-12 7.5 HIGH 9.8 CRITICAL
Buffer underflow in X.org libXvMC before 1.0.10 allows remote X servers to have unspecified impact via an empty string.
CVE-2016-7952 2 Fedoraproject, X.org 2 Fedora, Libxtst 2025-04-12 5.0 MEDIUM 7.5 HIGH
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.
CVE-2016-7947 2 Fedoraproject, X.org 2 Fedora, Libxrandr 2025-04-12 7.5 HIGH 9.8 CRITICAL
Multiple integer overflows in X.org libXrandr before 1.5.1 allow remote X servers to trigger out-of-bounds write operations via a crafted response.
CVE-2016-7945 2 Fedoraproject, X.org 2 Fedora, Libxi 2025-04-12 5.0 MEDIUM 7.5 HIGH
Multiple integer overflows in X.org libXi before 1.7.7 allow remote X servers to cause a denial of service (out-of-bounds memory access or infinite loop) via vectors involving length fields.
CVE-2016-7949 2 Fedoraproject, X.org 2 Fedora, Libxrender 2025-04-12 7.5 HIGH 9.8 CRITICAL
Multiple buffer overflows in the (1) XvQueryAdaptors and (2) XvQueryEncodings functions in X.org libXrender before 0.9.10 allow remote X servers to trigger out-of-bounds write operations via vectors involving length fields.
CVE-2016-7944 2 Fedoraproject, X.org 2 Fedora, Libxfixes 2025-04-12 7.5 HIGH 9.8 CRITICAL
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-2016-7950 2 Fedoraproject, X.org 2 Fedora, Libxrender 2025-04-12 7.5 HIGH 9.8 CRITICAL
The XRenderQueryFilters function in X.org libXrender before 0.9.10 allows remote X servers to trigger out-of-bounds write operations via vectors involving filter name lengths.
