Debian DSA-741-1 : bzip2 - infinite loop

medium Nessus Plugin ID 18645

Synopsis

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

Description

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

Solution

Upgrade the bzip2 package.

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.
