CVE-2024-31080

Name of the Vulnerable Software and Affected Versions Xorg-server (affected versions not specified)

Description The issue is related to a heap-based buffer over-read vulnerability in the ProcXIGetSelectedEvents() function of the X.org server. This occurs when byte-swapped length values are used in replies, potentially leading to memory leakage and segmentation faults, especially when triggered by a client with a different endianness. An attacker could exploit this to cause the X server to read heap memory values and transmit them back to the client until encountering an unmapped page, resulting in a crash. Although the attacker cannot control the specific memory copied into the replies, small length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds reads.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
