Vulnerability Assessment Details

Fedora Core 2 2004-239: libpng

Vulnerability Assessment Summary
Check for the version of the libpng package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory FEDORA-2004-239 (libpng).

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

several buffer overflows have been discovered in libpng. A possible hacker
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.
