Fedora 10 Update: libpng10-1.0.43-1.fc10

March 9, 2009

This release fixes a vulnerability in which some arrays of pointers are not initialized prior to using malloc to define the pointers

Summary

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.

This release fixes a vulnerability in which some arrays of pointers are not

initialized prior to using malloc to define the pointers. If the application

runs out of memory while executing the allocation loop (which can be forced by

malevolent input), libpng10 will jump to a cleanup process that attempts to free

all of the pointers, including the undefined ones. This issue has been

assigned CVE-2009-0040

* Thu Feb 19 2009 Paul Howarth 1.0.43-1

- update to 1.0.43 (clear pointer arrays created using png_malloc())

* Fri Dec 19 2008 Paul Howarth 1.0.42-1

- update to 1.0.42 (various minor bugfixes and code cleanups)
