HIGHCVSS v2 · 10.010.0—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 10.0 — 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:C/I:C/A:C. 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 62.7% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

Buffer overflow in Zinf 2.2.1 on Windows, and other older versions for Linux, allows remote attackers or local users to execute arbitrary code via certain values in a .pls file.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

What is CVE-2004-0964?
CVE-2004-0964 is a high vulnerability published on February 9, 2005. Buffer overflow in Zinf 2.2.1 on Windows, and other older versions for Linux, allows remote attackers or local users to execute arbitrary code via certain values in a .pls file.
When was CVE-2004-0964 disclosed?
CVE-2004-0964 was first published on February 9, 2005, with the most recent update on June 16, 2026. EchelonGraph re-ingests CVE updates from NVD on a 2-hour cycle, so this page reflects the latest published state.
Is CVE-2004-0964 actively exploited?
