| CVE-2023-6478 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-01-11 | N/A | 7.5 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-2023-6377 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-01-11 | 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-2023-5367 | 4 Debian, Fedoraproject, Redhat and 1 more | 5 Debian Linux, Fedora, Enterprise Linux and 2 more | 2024-01-10 | N/A | 7.8 HIGH |
| A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service. | |||||
| CVE-2023-5574 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2023-12-20 | 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-2022-46344 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2023-12-13 | 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-2023-3138 | 2 Redhat, X.org | 2 Enterprise Linux, Libx11 | 2023-12-08 | 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-2023-1393 | 2 Fedoraproject, X.org | 2 Fedora, Xorg-server | 2023-08-02 | N/A | 7.8 HIGH |
| A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later. | |||||
| CVE-2021-4010 | 3 Debian, Fedoraproject, X.org | 3 Debian Linux, Fedora, X Server | 2022-01-14 | 4.6 MEDIUM | 7.8 HIGH |

| CVE-2019-17624 | 1 X.org | 1 X Server | 2020-08-24 | 4.6 MEDIUM | 7.8 HIGH |
| "" In X.Org X Server 1.20.4, there is a stack-based buffer overflow in the function XQueryKeymap. For example, by sending ct.c_char 1000 times, an attacker can cause a denial of service (application crash) or possibly have unspecified other impact. Note: It is disputed if the X.Org X Server is involved or if there is a stack overflow. | |||||
| CVE-2017-2624 | 2 Debian, X.org | 2 Debian Linux, Xorg-server | 2019-10-09 | 1.9 LOW | 7.0 HIGH |
| 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-2018-14598 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2019-08-06 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault). | |||||
| CVE-2017-13723 | 2 Debian, X.org | 2 Debian Linux, Xorg-server | 2018-02-04 | 4.6 MEDIUM | 7.8 HIGH |
| 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-2015-3418 | 1 X.org | 1 Xorg-server | 2018-01-30 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-13720 | 1 X.org | 1 Libxfont | 2017-11-13 | 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 | 2017-11-13 | 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-2017-10971 | 1 X.org | 1 Xorg-server | 2017-11-04 | 6.5 MEDIUM | 8.8 HIGH |
| 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. | |||||
