Product : Fedora Core 2
Name : libpng
Version : 1.2.5
Release : 8
Summary : A library of functions for manipulating PNG image format
files.
Description :
The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. PNG is a bit-mapped graphics format similar to the GIF format. PNG was created to replace the GIF format, since GIF uses a patented data compression algorithm.

Libpng should be installed if you need to manipulate PNG format image files.

Update Information:

The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.

During a source code audit, Chris Evans discovered several buffer overflows in libpng. An attacker could create a carefully crafted PNG file in such a way that it would cause an application linked with libpng to execute arbitrary code when the file was opened by a victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0597 to these issues.

In addition, this audit discovered a potential NULL pointer dereference in libpng (CAN-2004-0598) and several integer overflow issues (CAN-2004-0599). An attacker could create a carefully crafted PNG file in such a way that it would cause an application linked with libpng to crash when the file was opened by the victim.

Red Hat would like to thank Chris Evans for discovering these issues.
