GStreamer rtpqdm2depay Out-Of-Bounds Write Remote Code Execution Vulnerability

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.1% (FIRST EPSS); higher than 66.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: gstreamer1-plugins-bad-free (AlmaLinux:10) 1.26.7-2.el10_2, 1.24.11-3.el10_1; gstreamer1-plugins-bad-free-devel (AlmaLinux:10) 1.26.7-2.el10_2, 1.24.11-3.el10_1; gstreamer1-plugins-bad-free-libs (AlmaLinux:10) 1.26.7-2.el10_2, 1.24.11-3.el10_1.

Low priority for now. Upgrade to gstreamer1-plugins-bad-free (AlmaLinux:10) 1.26.7-2.el10_2, 1.24.11-3.el10_1; gstreamer1-plugins-bad-free-devel (AlmaLinux:10) 1.26.7-2.el10_2, 1.24.11-3.el10_1; gstreamer1-plugins-bad-free-libs (AlmaLinux:10) 1.26.7-2.el10_2, 1.24.11-3.el10_1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

GStreamer rtpqdm2depay 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 X-QDM RTP payload elements. When parsing the packetid element, the process does not properly validate user-supplied data, which can result in a write past the end of an allocated array. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28850.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
