GHSA-9RPJ-3FH9-94X5

Vulnerability from github – Published: 2022-05-13 01:42 – Updated: 2022-05-13 01:42

Details

Bad reference counting in the context of accept_ice_connection() in gsm-xsmp-server.c in old versions of gnome-session up until version 2.29.92 allows a local attacker to establish ICE connections to gnome-session with invalid authentication data (an invalid magic cookie). Each failed authentication attempt will leak a file descriptor in gnome-session. When the maximum number of file descriptors is exhausted in the gnome-session process, it will enter an infinite loop trying to communicate without success, consuming 100% of the CPU. The graphical session associated with the gnome-session process will stop working correctly, because communication with gnome-session is no longer possible.

Severity

5.5 (Medium)
