Name of the Vulnerable Software and Affected Versions GNOME gvfs versions prior to 1.38.3 GNOME gvfs versions 1.40.x prior to 1.40.2 GNOME gvfs versions 1.41.x prior to 1.41.3

Description The issue is related to errors in the authorization procedure of the GVFS subsystem in the GNOME desktop environment for Linux operating systems. A local attacker could connect to the D-Bus server socket and issue D-Bus method calls, potentially allowing them to exploit the vulnerability. The server socket only accepts a single connection, so the attacker would have to discover the server and connect to the socket before its owner does.

Recommendations For versions prior to 1.38.3, update to version 1.38.3 or later. For versions 1.40.x prior to 1.40.2, update to version 1.40.2 or later. For versions 1.41.x prior to 1.41.3, update to version 1.41.3 or later.
