An integer overflow vulnerability in the AV1 LEB128 variable-length integer parser allows a remote attacker to cause a crash in applications that process AV1 media content. By crafting a malformed AV1 bitstream containing an invalid LEB128-encoded value, an attacker can cause integer overflow in the parser, resulting in incorrect length values being used during stream processing, which can lead to a denial of service.\n\n## Affected\n\n- `gstreamer1-plugins-bad-free (all versions)`\n- `gstreamer1-plugins-base (all versions)`\n- `gstreamer-plugins-bad-free`\n- `gstreamer-plugins-base`\n- `gstreamer1-plugins-bad-free`\n- `gstreamer1-plugins-base`\n- `gstreamer-plugins-bad-free`\n- `gstreamer-plugins-base`\n- `gstreamer1-plugins-bad-free`\n- `gstreamer1-plugins-base`\n- `gstreamer1-plugins-bad-free (all versions)`\n- `gstreamer1-plugins-base (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nNo mitigation is currently available that meets Red Hat Product Security's standards for usability, deployment, applicability, or stability.","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
