| Summary | Integer overflow leading to heap overwrite in RealMedia file handling |

|
## Details
|
||
|
|
|
||
|
|
Heap-based buffer overflow in the RealMedia file demuxer when handling malformed files in GStreamer versions before 1.22.5 / 1.20.7.
|
||
|
|
|
||
|
|
## Impact
|
||
|
|
|
||
|
|
It is possible for a malicious third party to trigger a crash in the application, and possibly also effect code execution through heap manipulation.
|
||
|
|
|
||
|
|
## Solution
|
||
|
|
|
||
|
|
The gst-plugins-ugly 1.22.5 / 1.20.7 releases address the issue. People using older branches of GStreamer should apply the patch and recompile.
