Description:
Jan Braun has reported a vulnerability in fbida, which can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.

The "fbgs" script creates temporary files insecurely in the "/var/tmp" directory when the "TMPDIR" environment variable isn't defined. This can be exploited to create or overwrite arbitrary files via symlink attacks with the privileges of a user running the vulnerable script.

The vulnerability has been reported in versions 2.01 and 2.03. Other versions may also be affected.
