## Description

GStreamer rtpqdm2depay Heap-based Buffer Overflow Remote Code Execution
Vulnerability. This vulnerability allows remote attackers to execute
arbitrary code on affected installations of GStreamer. Interaction with
this library is required to exploit this vulnerability but attack vectors
may vary depending on the implementation.
The specific flaw exists within the processing of X-QDM RTP payloads. The
issue results from the lack of proper validation of the length of
user-supplied data prior to copying it to a heap-based buffer. An attacker
can leverage this vulnerability to execute code in the context of the
current process. Was ZDI-CAN-28851.
