CVE-2009-0385

Status: ModifiedHigh (9.3)—

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.

CVSS
