CVE-2013-6420

Disclosure Date: December 17, 2013 •
CVE-2013-6420
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

The asn1_time_to_time_t function in ext/openssl/openssl.c in PHP before 5.3.28, 5.4.x before 5.4.23, and 5.5.x before 5.5.7 does not properly parse (1) notBefore and (2) notAfter timestamps in X.509 certificates, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted certificate that is not properly handled by the openssl_x509_parse function.
