Vulnerability Assessment Summary
DSA-1149-1 ncompress

Detailed Explanation for this Vulnerability Assessment

Tavis Ormandy from the Google Security Team discovered a missing
boundary check in ncompress, the original Lempel-Ziv compress and
uncompress programs, which permits a specially crafted datastream to
underflow a buffer with attacker controlled data.
For the stable distribution (sarge) this problem has been fixed in
version 4.2.4-15sarge2.
For the unstable distribution (sid) this problem has been fixed in
version 4.2.4-15sarge2.
We recommend that you upgrade your ncompress package.
