[SECURITY] Fedora 7 Update: libpng10-1.0.26-1.fc7.1

--------------------------------------------------------------------------------
Fedora Update Notification
FEDORA-2007-0004 (Corrected)
None
--------------------------------------------------------------------------------

Name        : libpng10
Product     : Fedora 7
Version     : 1.0.26
Release     : 1.fc7.1
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:

The png_handle_tRNS function in pngrutil.c in libpng before 1.0.25 and 1.2.x
before 1.2.17 allows remote attackers to cause a denial of service
(application crash) via a grayscale PNG image with a bad tRNS chunk CRC value.

This update to libpng 1.0.26 resolves this problem.
