medium Nessus Plugin ID 15153
Synopsis
The remote Debian host is missing a security-related update.Description
The nethack and slashem packages are vulnerable to a buffer overflow exploited via a long '-s' command line option. This vulnerability could be used by an attacker to gain gid 'games' on a system where nethack is installed.Additionally, some setgid binaries in the nethack package have incorrect permissions, which could allow a user who gains gid 'games' to replace these binaries, potentially causing other users to execute malicious code when they run nethack.
Note that slashem does not contain the file permission problem CAN-2003-0359.
Solution
