## Details

GStreamer before 1.16.0 has a heap-based buffer overflow in the RTSP connection parser via a crafted response from a server.

## Impact

The potential exists for a malicious server to trigger remote code execution in a connecting client.

## Threat mitigation

Exploitation requires the user to access a malicious RTSP server.

## Workarounds

The user should refrain from opening RTSP streams from untrusted third parties

## Solution

The gst-plugins-base 1.16.0 release addresses the issue. People using older branches of GStreamer should apply the patch and recompile.
