Debian Security Advisory DSA 1149-1 [email protected]
http://www.debian.org/security/ Martin Schulze
August 10th, 2006 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
Package : ncompress
Vulnerability : buffer underflow
Problem type : local (remote)
Debian-specific: no
CVE ID : CVE-2006-1168
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.
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.
