Debian DSA-2112-1 : bzip2 - integer overflow
Medium Nessus Plugin ID 49291
SynopsisThe remote Debian host is missing a security-related update.
DescriptionMikolaj Izdebski has discovered an integer overflow flaw in the BZ2_decompress function in bzip2/libbz2. An attacker could use a crafted bz2 file to cause a denial of service (application crash) or potentially to execute arbitrary code. (CVE-2010-0405 )
SolutionUpgrade the bzip2 / dpkg packages.
After the upgrade, all running services that use libbz2 need to be restarted.
This update also provides rebuilt dpkg packages, which are statically linked to the fixed version of libbz2. Updated packages for clamav, which is also affected by this issue, will be provided on debian-volatile.
For the stable distribution (lenny), this problem has been fixed in version 1.0.5-1+lenny1.
