CVE-2025-47183: In GStreamer through 1.26.1, the isomp4 plugin's qtdemux_parse_tree function may read past the end of a heap buffer while parsing an MP4 fil

Noroxi assessment

Priority: Monitor (action score 26/100)

  • 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: 0.21% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: gst-plugins-good (Alpine:v3.22) 1.26.2-r0; gst-plugins-good1.0 (Debian:11) 1.18.4-2+deb11u4; gst-plugins-good1.0 (Debian:12) 1.22.0-5+deb12u4.

Low priority for now. Upgrade to gst-plugins-good (Alpine:v3.22) 1.26.2-r0; gst-plugins-good1.0 (Debian:11) 1.18.4-2+deb11u4; gst-plugins-good1.0 (Debian:12) 1.22.0-5+deb12u4 or later.
