Description


Steve Kemp has reported a vulnerability in Petris, which potentially can be exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to a boundary error in the handling of environment variables when processing highscores. This can be exploited to cause a buffer overflow.

Successful exploitation may allow execution of arbitrary code with escalated privileges on systems, where the game has been installed setuid or setgid (typically setgid "games").


Solution:
Remove any setuid / setgid bits.
