Reference: URL:http://xforce.iss.net/xforce/xfdb/48330

Integer signedness error in the fourxm_read_header function in
libavformat/4xm.c in FFmpeg before revision 16846 allows remote
attackers to execute arbitrary code via a malformed 4X movie file with
a large current_track value, which triggers a NULL pointer
dereference.
