| CVE-2017-13721 | 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, 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-2017-13723 | 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-2017-2624 | 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. | ||||

| 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-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-2017-10971 | 1 X.org | 1 X Server | 2025-08-29 | 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-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.
