Base vector

AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions: libXdmcp versions prior to 1.1.2

Description: A weakness in entropy used for generating session keys was found. On a multi-user system using xdmcp, a local attacker could potentially use information from the process list to brute force the key, allowing them to hijack other users' sessions.

Recommendations: For versions prior to 1.1.2, update to version 1.1.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the system to minimize the risk of exploitation.
