The nss_dns implementation of getnetbyname in GNU C Library (aka glibc) before 2.21, when the DNS backend in the Name Service Switch configuration is enabled, allows remote attackers to cause a denial of service (infinite loop) by sending a positive answer while a network name is being process.
CVE-2014-9402
This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 7.8 — 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:N/I:N/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 7.8% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

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).
