Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU99493

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-9632

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the XkbSetCompatMap() function in xkb/xkb.c. A local user can pass a specially crafted bitmap to the X.Org server, trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.

Mitigation

Update the affected packages.
x11-base/xorg-server to version: 21.1.14
x11-base/xwayland to version: 24.1.4

Vulnerable software versions

Gentoo Linux: All versions

x11-base/xwayland: before 24.1.4

x11-base/xorg-server: before 21.1.14
