nethack - buffer overflow, incorrect permissions



Debian Security Advisory

DSA-316-1 nethack -- buffer overflow, incorrect permissions

Date Reported:
11 Jun 2003
Affected Packages:
nethack
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CAN-2003-0358, CAN-2003-0359.
More information:

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.

For the stable distribution (woody) these problems have been fixed in version 3.4.0-3.0woody3.

For the old stable distribution (potato) these problems have been fixed in version 3.3.0-7potato1.

For the unstable distribution (sid) these problems are fixed in version 3.4.1-1.

We recommend that you update your nethack package.

For the stable distribution (woody) these problems have been fixed in version 0.0.6E4F8-4.0woody3.

For the old stable distribution (potato) these problems have been fixed in version 0.0.5E7-3potato1.

For the unstable distribution (sid) these problems are fixed in version 0.0.6E4F8-6.

We recommend that you update your slashem package.

Fixed in:

Debian GNU/Linux 2.2 (potato)
