Vulnerability Details

CVE-ID: CVE-2014-3567

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak when handling failed session ticket integrity checks. By sending an overly large number of invalid session tickets, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server.

CVSS Base Score: 5.0
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/97036&gt; for more information
