[SECURITY] Fedora 15 Update: gnash-0.8.10-2.fc15

Gnash is capable of reading up to SWF v9 files and op-codes, but primarily supports SWF v7, with better SWF v8 and v9 support under heavy development. Gnash includes initial parser support for SWF v8 and v9. Not all ActionScript 2 classes are implemented yet, but all of the most heavily used ones are. Many ActionScript 2 classes are partially implemented; there is support for all of the commonly used methods of each class.
