Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The ZDI has assigned a CVSS rating of 8.8. The following CVEs are assigned: CVE-2026-3085.
AI Analysis
Technical Summary
CVE-2026-3085 is a critical remote code execution vulnerability in GStreamer's rtpqdm2depay component caused by insufficient validation of the length of user-supplied data prior to copying it into a heap-based buffer. This heap-based buffer overflow can be triggered remotely via crafted X-QDM RTP payloads. Successful exploitation enables an attacker to execute arbitrary code with the privileges of the affected process. The vulnerability has a CVSS score of 8.8 and was publicly disclosed on March 6, 2026. GStreamer has issued an official patch to remediate this flaw.
Potential Impact
Remote attackers can exploit this vulnerability to execute arbitrary code on systems running vulnerable versions of GStreamer. This can lead to full compromise of the affected process, including potential data corruption, denial of service, or further system compromise depending on the context in which GStreamer is used.
Mitigation Recommendations
An official patch has been released by GStreamer to fix this vulnerability. Users and administrators should apply the update available at https://gitlab.freedesktop.org/gstreamer/gstreamer/-/commit/d60a94dee3c0a0942c9981491bf83e0de1900fbf to remediate the issue. No additional mitigation steps are indicated by the vendor advisory.
