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 Media RewriteODFrame 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 using a specially created file. No information is provided about the estimated number of potentially affected devices or real-world incidents.

Recommendations For GPAC version 1.0.1, consider disabling the Media RewriteODFrame function as a temporary workaround until a patch is available. Restrict access to the MP4Box command to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
