| 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-2023-6478 | 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-2023-5367 | 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-2023-43788 | 3 Fedoraproject, Redhat, X.org | 3 Fedora, Enterprise Linux, Libxpm | 2023-12-22 | N/A | 5.5 MEDIUM |
| A vulnerability was found in libXpm due to a boundary condition within the XpmCreateXpmImageFromBuffer() function. This flaw allows a local attacker to trigger an out-of-bounds read error and read the contents of memory on the system. | |||||
| 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-2023-5380 | 4 Debian, Fedoraproject, Redhat and 1 more | 5 Debian Linux, Fedora, Enterprise Linux and 2 more | 2023-11-30 | N/A | 4.7 MEDIUM |
| A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in 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 within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed. | |||||
| 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-2020-14362 | 1 X.org | 1 Xorg-server | 2021-11-04 | 4.6 MEDIUM | 7.8 HIGH |
| A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-14346 | 1 X.org | 1 Xorg-server | 2021-11-04 | 4.6 MEDIUM | 7.8 HIGH |
| A flaw was found in xorg-x11-server before 1.20.9. An integer underflow in the X input extension protocol decoding in the X server may lead to arbitrary access of memory contents. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-14361 | 1 X.org | 1 Xorg-server | 2021-11-04 | 4.6 MEDIUM | 7.8 HIGH |
| A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-14363 | 2 Fedoraproject, X.org | 2 Fedora, Libx11 | 2021-11-04 | 4.6 MEDIUM | 7.8 HIGH |
| An integer overflow vulnerability leading to a double-free was found in libX11. This flaw allows a local privileged attacker to cause an application compiled with libX11 to crash, or in some cases, result in arbitrary code execution. The highest threat from this flaw is to confidentiality, integrity as well as system availability. | |||||
| CVE-2021-31535 | 2 Fedoraproject, X.org | 3 Fedora, Libx11, X Window System | 2021-09-23 | 7.5 HIGH | 9.8 CRITICAL |
| LookupCol.c in X.Org X through X11R7.7 and libX11 before 1.7.1 might allow remote attackers to execute arbitrary code. The libX11 XLookupColor request (intended for server-side color lookup) contains a flaw allowing a client to send color-name requests with a name longer than the maximum size allowed by the protocol (and also longer than the maximum packet size for normal-sized packets). The user-controlled data exceeding the maximum size is then interpreted by the server as additional X protocol requests and executed, e.g., to disable X server authorization completely. For example, if the victim encounters malicious terminal control sequences for color codes, then the attacker may be able to take full control of the running graphical session. | |||||
| CVE-2021-3472 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2021-05-19 | 7.2 HIGH | 7.8 HIGH |

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-2011-4029 | 1 X.org | 1 X Server | 2020-08-24 | 1.9 LOW | N/A |
| The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to change the permissions of arbitrary files to 444, read those files, and possibly cause a denial of service (removed execution permission) via a symlink attack on a temporary lock file. | |||||

| 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. | |||||
