Debian Security Advisory DSA 741-1 Martin Schulze
July 7th, 2005

Package : bzip2
Vulnerability : infinite loop
Problem-Type : local (remote)
Debian-specific: no
CVE ID : CAN-2005-1260
Debian Bug : 310803

Chris Evans discovered that a specially crafted archive can trigger an infinete loop in bzip2, a high-quality block-sorting file compressor. During uncompression this results in an indefinitively growing output file which will finally fill up the disk and. On systems that automatically decompress bzip2 archives this can cause a denial of service.

For the oldstable distribution (woody) this problem has been fixed in version 1.0.2-1.woody5.

For the stable distribution (sarge) this problem has been fixed in version 1.0.2-7.

For the unstable distribution (sid) this problem has been fixed in version 1.0.2-7.

We recommend that you upgrade your bzip2 package.
