Fedora 9 : libpng10-1.0.37-1.fc9 (2008-3683)

High Nessus Plugin ID 32458


The remote Fedora host is missing a security update.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libpng10 package.
