Name of the Vulnerable Software and Affected Versions GPAC version 1.0.1

Description The issue is related to a heap buffer overflow in the URL GetProtocolType function of the MP4Box command in the GPAC multimedia platform. This can be exploited by a remote attacker using a specially crafted file, potentially leading to a denial of service or the execution of arbitrary code.

Recommendations For GPAC version 1.0.1, consider disabling the URL GetProtocolType 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 heap buffer overflow in the URL GetProtocolType function. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
