The LoadString function in helper.h in libgig 4.0.0 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted gig file.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
