CVE-2015-1793
Last modified
CVE-2015-1793 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 61.80% chance of exploitation in the next 30 days.
