Debian Security Advisory DSA 498-1 security@debian.org

April 30th, 2004 http://www.debian.org/security/faq
- --------------------------------------------------------------------------

Package : libpng, libpng3
Vulnerability : out of bound access
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2004-0421

Steve Grubb discovered a problem in the Portable Network Graphics
library libpng which is utilised in several applications. When
processing a broken PNG image, the error handling routine will access
memory that is out of bounds when creating an error message.
Depending on machine architecture, bounds checking and other
protective measures, this problem could cause the program to crash if
a defective or intentionally prepared PNG image file is handled by
libpng.

This could be used as a denial of service attack against various
programs that link against this library. The following commands will
show you which packages utilise this library and whose programs should
probably restarted after an upgrade:

apt-cache showpkg libpng2
apt-cache showpkg libpng3

The following security matrix explains which package versions will
contain a correction.

Package stable (woody) unstable (sid)
libpng 1.0.12-3.woody.5 1.0.15-5
libpng3 1.2.1-1.1.woody.5 1.2.5.0-6

We recommend that you upgrade your libpng and related 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.

Debian GNU/Linux 3.0 alias woody
