DSA 140-2-libpng, libpng3

by Nikola Strahija on August 6th, 2002 In addition to the advisory DSA 140-1 the packages below fix another potential buffer overflow. The PNG libraries implement a safety margin which is also included in a newer upstream release. Thanks to Glenn Randers-Pehrson for informing us.


This problem has been fixed in version 1.0.12-3.woody.2 of libpng and
version 1.2.1-1.1.woody.2 of libpng3 for the current stable
distribution (woody).

We recommend that you upgrade your libpng packages.

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.
