Debian: New Perl packages fix arbitrary code execution

Date 27 Jan 2006
Posted By Joe Shakespeare
Jack Louis discovered an integer overflow in Perl, Larry Wall's Practical Extraction and Report Language, that allows attackers to overwrite arbitrary memory and possibly execute arbitrary code via specially crafted content that is passed to vulnerable format strings of third party software.

Package        : perl
Vulnerability  : integer overflow
Problem type   : local (remote)
Debian-specific: no
CVE ID         : CVE-2005-3962
Debian Bug     : 341542

Jack Louis discovered an integer overflow in Perl, Larry Wall's
Practical Extraction and Report Language, that allows attackers to
overwrite arbitrary memory and possibly execute arbitrary code via
specially crafted content that is passed to vulnerable format strings
of third party software.

The old stable distribution (woody) does not seem to be affected by
this problem.

For the stable distribution (sarge) this problem has been fixed in
version 5.8.4-8sarge3.

For the unstable distribution (sid) this problem has been fixed in
version 5.8.7-9.

We recommend that you upgrade your perl 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.
