--------------------------------------------------------------------- Fedora Update Notification FEDORA-2005-1046 2005-11-03 --------------------------------------------------------------------- Product : Fedora Core 4 Name : libungif Version : 4.1.3 Release : 3.fc4.2 Summary : A library for manipulating GIF format image files. Description : The libungif package contains a shared library of functions for loading and saving GIF format image files. The libungif library can load any GIF file, but it will save GIFs only in uncompressed format (i.e., it won't use the patented LZW compression used to save "normal" compressed GIF files). Install the libungif package if you need to manipulate GIF files. You should also install the libungif-progs package. --------------------------------------------------------------------- Update Information: The libungif package contains a shared library of functions for loading and saving GIF format image files. The libungif library can load any GIF file, but it will save GIFs only in uncompressed format; it will not use the patented LZW compression used to save "normal" compressed GIF files. A bug was found in the way libungif handles colormaps. An attacker could create a GIF file in such a way that could cause out-of-bounds writes and register corruptions. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-2974 to this issue. All users of libungif should upgrade to the updated packages, which contain a backported patch to resolve this issue. --------------------------------------------------------------------- * Fri Oct 21 2005 Matthias Clasen |
