REDHAT-BUG-2520605: Use After Free
GStreamer rtpsbcdepay Use-After-Free 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 RTP payload elements. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29787.

Frequently Asked Questions
Which deployments are realistically exposed?
Deployments that use the affected GStreamer rtpsbcdepay component and process RTP payload elements are relevant. Whether a reachable remote attack path exists depends on how the library is integrated into the application.
What does an attacker need to exploit the issue?
The attacker needs interaction with the affected library. The available attack vector can vary by implementation, but the flaw is triggered during RTP payload element processing.
What is the impact if exploitation succeeds?
A successful exploit can allow arbitrary code execution in the context of the current process. The issue is a use-after-free caused by operating on an object without validating that it exists.
