OSVDB: OSVDB-74439

Adobe Flash Player MP4 SequenceParameterSetNALUnit Buffer Overflow
Posted Feb 10, 2012
Authored by Abysssec, sinn3r, Alexander Gavrun | Site metasploit.com

This Metasploit module exploits a vulnerability found in Adobe Flash Player's Flash10u.ocx component. When processing a MP4 file (specifically the Sequence Parameter Set), Flash will see if pic_order_cnt_type is equal to 1, which sets the num_ref_frames_in_pic_order_cnt_cycle field, and then blindly copies data in offset_for_ref_frame on the stack, which allows arbitrary remote code execution under the context of the user. Numerous reports also indicate that this vulnerability has been exploited in the wild. Please note that the exploit requires a SWF media player in order to trigger the bug, which currently isn't included in the framework. However, software such as Longtail SWF Player is free for non-commercial use, and is easily obtainable.
