7.1

High

Base vector

AV:N/AC:M/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions GPAC version 1.0.1

Description The issue is related to the abst box size function in the MP4Box command, which allows attackers to cause a denial of service (NULL pointer dereference) via a crafted file. This can be exploited by a remote attacker to disrupt service.

Recommendations For GPAC version 1.0.1, consider disabling the abst box size function as a temporary workaround until a patch is available. Restrict access to the MP4Box command to minimize the risk of exploitation. Avoid using crafted files that could trigger the NULL pointer dereference.
