NOTE: this issue might not be a vulnerability, since the ability to set this option typically implies that the attacker already has legitimate access to cause a DoS or execute code, and therefore the issue would not cross privilege boundaries. There may be limited attack scenarios if isql command-line options are exposed to an attacker, although it seems likely that other, more serious issues would also be exposed, and this issue might not cross privilege boundaries in that context.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-119"],"references":["http://www.openwall.com/lists/oss-security/2012/05/29/10","http://www.openwall.com/lists/oss-security/2012/05/29/7","http://www.openwall.com/lists/oss-security/2012/05/30/7","http://www.openwall.com/lists/oss-security/2012/05/31/2","http://www.openwall.com/lists/oss-security/2012/06/06/3"],"products":["unixodbc:unixodbc"],"source":"nvd","synced_at":"2026-10-19T20:25:53.526315492+00:00"},"epss":{"cve":"CVE-2012-2657","score":0.00443,"percentile":0.38497,"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).
