CVE-2011-3623

HIGHCVSS v2 · 7.57.5—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 7.5 — v2 rates that HIGH (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:L/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 4.3% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

Multiple stack-based buffer overflows in VideoLAN VLC media player before 1.0.2 allow remote attackers to execute arbitrary code via (1) a crafted ASF file, related to the ASF_ObjectDumpDebug function in modules/demux/asf/libasf.c; (2) a crafted AVI file, related to the AVI_ChunkDumpDebug_level function in modules/demux/avi/libavi.c; or (3) a crafted MP4 file, related to the __MP4_BoxDumpStructure function in modules/demux/mp4/libmp4.c.
