Fedora Update Notification
FEDORA-2008-3937
2008-05-28 22:53:49
--------------------------------------------------------------------------------
Name : libpng10
Product : Fedora 8
Version : 1.0.37
Release : 1.fc8
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:
This update fixes the way that libpng10 handles unknown zero-length chunks,
which in previous versions could result in writing to attacker controlled
addresses, depending on how the libpng api is used. To be affected, an
application would have to call png_set_keep_unknown_chunks(), which tells libpng
not to ignore unknown chunks, but to do something with them. The PNG spec
allows for "unknown" chunks, which are ignored by default, but an application
could in theory embed some sort of extra data in a png image, then later get it
back out via this mechanism. No packages in Fedora are believed to be
affected by this issue, but it's possible that third-party applications could
be.
