Release     : 1.fc17
URL         : http://www.libpng.org/pub/png/libpng.html
Summary     : Old version of libpng, needed to run old binaries
Description :
The libpng10 package contains an old version of libpng, a library of functions
for creating and manipulating PNG (Portable Network Graphics) image format
files.

This package is needed if you want to run binaries that were linked dynamically
with libpng 1.0.x.

--------------------------------------------------------------------------------
Update Information:

A type conversion flaw leading to an out-of-bounds heap buffer read was found in the way libpng10, a library of functions for manipulation PNG image format files, performed expansion of certain iCCP, iTXt, and zTXt PNG image file chunks.

A remote attacker could provide a specially-crafted Portable Network Graphics (PNG) image file, which once opened in an application, linked against libpng10, could lead to denial of service or in some cases, execution of arbitrary code without permission of the user running such an application.
