CVE-2011-1658

LOWCVSS v2 · 3.73.7—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 3.7 — v2 rates that LOW (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:L/AC:H/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 0.3% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

ld.so in the GNU C Library (aka glibc or libc6) 2.13 and earlier expands the $ORIGIN dynamic string token when RPATH is composed entirely of this token, which might allow local users to gain privileges by creating a hard link in an arbitrary directory to a (1) setuid or (2) setgid program with this RPATH value, and then executing the program with a crafted value for the LD_PRELOAD environment variable, a different vulnerability than CVE-2010-3847 and CVE-2011-0536. NOTE: it is not expected that any standard operating-system distribution would ship an applicable setuid or setgid program.

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).
