OpenSSL is vulnerable to buffer overflow. The vulnerability exists due to incomplete X.509 certificate name constraint checking after successful chain signature verification. An attacker can add a malicious email address to the certificate to overflow an arbitrary number of bytes on the stack with the . character. This crash can result in denial of service.
