CVE-2009-0385: Null Pointer Dereference
First published: Mon Feb 02 2009(Updated: )
FFmpeg could allow a remote attacker to execute arbitrary code on the system, caused by an integer signedness error in the fourxm_read_header() function in libavformat/4xm.c. By persuading a victim to open a specially-crafted 4X movie file with a large current_track value, a remote attacker could exploit this vulnerability to corrupt memory, trigger a NULL pointer dereference and execute arbitrary code on the system.
