CVE-2026-119843

MediumCVSS 6.5
Published: Updated: Translated: NVD NIST

Summary

A flaw was found in GStreamer's gst-plugins-good package. The FLV media demuxer does not properly validate buffer sizes and data availability when processing enhanced audio and video tags in malformed or truncated FLV streams. A remote attacker could exploit this vulnerability by providing a specially crafted FLV media file that, when opened or streamed by a GStreamer-based application, triggers an assertion failure or a process crash, leading to denial of service.

Risk Assessment

Denial of service (DoS) is possible for applications processing untrusted media files, potentially disrupting service availability.

Recommendation

Update the gst-plugins-good package to a version containing the fix and avoid processing untrusted FLV files in critical services.
