Name of the Vulnerable Software and Affected Versions GPAC version 1.0.1

Description The issue is related to the gf media export filters function in the MP4Box command of the GPAC multimedia platform, which is associated with NULL pointer dereference errors. This allows a remote attacker to cause a denial of service using a specially crafted file.

Recommendations For GPAC version 1.0.1, consider disabling the gf media export filters function as a temporary workaround until a patch is available.
