GStreamer RealMedia Demuxer Out-Of-Bounds Write 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 video packets. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28845.
AnalysisAI
Critical remote code execution vulnerability in GStreamer's RealMedia demuxer component, allowing attackers to execute arbitrary code via malformed video packets that trigger an out-of-bounds write. The vulnerability affects all versions of GStreamer (CPE indicates wildcard versioning) and requires user interaction to process malicious media files. …

RemediationAI
Within 24 hours: Inventory all systems running GStreamer and assess exposure based on user workflows involving media file processing. Within 7 days: Implement compensating controls (disable RealMedia demuxer, restrict file upload sources, deploy network segmentation for media processing systems) and establish user awareness to avoid opening untrusted video files. …
