Description:
A vulnerability has been identified in XBoard, which can be exploited by malicious, local users to escalate their privileges.
The problem is that XBoard creates a file with a predictable name in the "/tmp" directory. This can potentially be exploited to manipulate arbitrary files and escalate privileges via symlink attacks.
Version 4.2.6 and prior are vulnerable.
Solution:
Update to version 4.2.7:
http://ftp.gnu.org/gnu/xboard/xboard-4.2.7.tar.gz
