CVE-2012-0859

MEDIUMCVSS v2 · 6.86.8—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 6.8 — v2 rates that MEDIUM (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:N/AC:M/Au:N/C:P/I:P/A:P. CVSS v2 is an older, coarser metric than v3.1/v4.0 (no Scope, no User Interaction, no Attack Requirements), so it is not directly comparable to a v3 or v4 score. NVD has never re-scored this record under v3. EPSS predicts 4.0% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

A fix is available — apply it.

The render_line function in the vorbis codec (vorbis.c) in libavcodec in FFmpeg before 0.9.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted Vorbis file, related to a large multiplier. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3893.
