[SECURITY] [DSA 213-1] New libpng packages fix buffer overflow

by Nikola Strahija on December 19th, 2002 . The starting offsets for the loops are calculated incorrectly which causes a buffer overrun beyond the beginning of the row buffer.

Package : libpng, libpng3
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE Id : CAN-2002-1363

Glenn Randers-Pehrson discovered a problem in connection with 16-bit
samples from libpng, an interface for reading and writing PNG
(Portable Network Graphics) format files. The starting offsets for
the loops are calculated incorrectly which causes a buffer overrun
beyond the beginning of the row buffer.

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

For the old stable distribution (potato) this problem has been fixed
in version 1.0.5-1.1 for libpng. There are no other libpng packages.

For the unstable distribution (sid) this problem has been fixed in
version 1.0.12-7 for libpng and in version 1.2.5-8 for libpng3.

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.
