Out-of-Bounds Read in GStreamer's gst-plugins-good (CVE-2026-17072)
Summary
Vulnerability in GStreamer's gst-plugins-good (CVE-2026-17072). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
A flaw was found in GStreamer's gst-plugins-good. A heap-based out-of-bounds read of 4 bytes can occur when parsing FLAC audio stream headers embedded in a Matroska or WebM container file. The vulnerability is triggered by a boundary check that does not account for the full size of the data being copied, allowing a small read past the end of the allocated buffer. An attacker could exploit this by crafting a malicious Matroska or WebM file and tricking a user into opening it, potentially leaking a small amount of adjacent heap memory.
