openssl: openssl-src: OpenSSL: Memory leak leads to Denial of Service in OCSP response checking

A flaw was found in OpenSSL. A malicious TLS Transport Layer Security server can exploit this vulnerability by sending a specially crafted OCSP Online Certificate Status Protocol response during the X.509 certificate chain verification process. This can lead to a memory leak in client application...
