This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects OpenBSD 6.1 and possibly earlier versions.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","score":6.5},"cwes":["CWE-400"],"references":["http://www.securityfocus.com/bid/99177","http://www.securitytracker.com/id/1039427","https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libc/stdlib/qsort.c?rev=1.15&content-type=text/x-cvsweb-markup","https://support.apple.com/HT208112","https://support.apple.com/HT208113"],"products":["openbsd:openbsd"],"source":"nvd","synced_at":"2026-10-19T20:43:44.556243339+00:00"},"epss":{"cve":"CVE-2017-1000373","score":0.1338,"percentile":0.96419,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
