Debian: DSA-2112-1: New bzip2 packages fix integer overflow

Date 20 Sep 2010
Posted By LinuxSecurity Advisories
Mikolaj 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)

Package        : bzip2
Vulnerability  : integer overflow
Problem type   : local (remote)
Debian-specific: no
CVE Id(s)      : CVE-2010-0405

Mikolaj 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)

After the upgrade, all running services that use libbz2 need to be

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), these problems have been fixed in
version 1.0.4-1+lenny1.

For the testing distribution (squeeze) and the unstable distribution (sid),
this problem in bzip2 will be fixed soon. Updated dpkg packages are not
necessary for testing/unstable.

We recommend that you upgrade your bzip2 / dpkg packages.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

After having upgraded the package, you need to restart all processes using
libbz2. The script checkrestart from the debian-goodies package or lsof
may help to find out which processes are still using the old libbz2.
