Debian DSA-1149-1 : ncompress - buffer underflow

high Nessus Plugin ID 22691

Synopsis

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

Description

Tavis Ormandy from the Google Security Team discovered a missing boundary check in ncompress, the original Lempel-Ziv compress and uncompress programs, which allows a specially crafted datastream to underflow a buffer with attacker controlled data.

Solution

Upgrade the ncompress package.

For the stable distribution (sarge) this problem has been fixed in version 4.2.4-15sarge2.
