FKIE_CVE-2015-1793
Vulnerability from fkie_nvd - Published: 2015-07-09 19:17 - Updated: 2026-06-17 00:23
Severity
Summary
The X509_verify_cert function in crypto/x509/x509_vfy.c in OpenSSL 1.0.1n, 1.0.1o, 1.0.2b, and 1.0.2c does not properly process X.509 Basic Constraints cA values during identification of alternative certificate chains, which allows remote attackers to spoof a Certification Authority role and trigger unintended certificate verifications via a valid leaf certificate.
