Note: Versions mentioned in the description apply only to the upstream libextractor package and not the libextractor package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

GNU Libextractor 1.6 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted GIF, IT (Impulse Tracker), NSFE, S3M (Scream Tracker 3), SID, or XM (eXtended Module) file, as demonstrated by the EXTRACTOR_xm_extract_method function in plugins/xm_extractor.c.
