Name of the Vulnerable Software and Affected Versions gpac versions prior to 20200801

Description The issue is related to a stack-buffer-overflow in the DumpRawUIConfig function located in the odf dump.c file of the GPAC multimedia platform. This allows a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The vulnerability also enables an attacker to cause code execution.

Restrict access to the odf dump.c file to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
