Description:
Javier Fernandez-Sanguino Pena has reported a vulnerability in mgdiff Patch Viewer, which can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.
The vulnerability is caused due to "viewpatch" script creating temporary files insecurely in "/tmp". This can be exploited via symlink attacks to create or overwrite arbitrary files with the privileges of the user running the affected script.
Solution:
Grant only trusted users access to affected systems.
