Debian DSA-193-1 : kdenetwork - buffer overflow

high Nessus Plugin ID 15030

Synopsis

The remote Debian host is missing a security-related update.

Description

iDEFENSE reports a security vulnerability in the klisa package, that provides a LAN information service similar to 'Network Neighbourhood', which was discovered by Texonet. It is possible for a local attacker to exploit a buffer overflow condition in resLISa, a restricted version of KLISa. The vulnerability exists in the parsing of the LOGNAME environment variable, an overly long value will overwrite the instruction pointer thereby allowing an attacker to seize control of the executable.

Solution

Upgrade the klisa package immediately.

This problem has been fixed in version 2.2.2-14.2 for the current stable distribution (woody) and in version 2.2.2-14.3 for the unstable distribution (sid). The old stable distribution (potato) is not affected since it doesn't contain a kdenetwork package.
