OpenSSL is used by IBM Workload Deployer. IBM Workload Deployer has addressed the applicable CVEs and included the SSL 3.0 Fallback protection (TLS_FALLBACK_SCSV) provided by OpenSSL. Vulnerability Details CVEID: CVE-2014-3513 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak in the DTLS Secure Real-time Transport Protocol (SRTP) extension parsing code. By sending multiple specially-crafted handshake messages, 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 http://xforce.iss.net/xforce/xfdb/97035 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: 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 http://xforce.iss.net/xforce/xfdb/97036 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2014-3568 DESCRIPTION: OpenSSL could allow a remote attacker bypass security restrictions. When configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake. An attacker could exploit this vulnerability to perform unauthorized actions. CVSS Base Score: 2.6 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97037 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N) Affected Products and Versions IBM Workload Deployer version 3.1 and later Remediation/Fixes The solution is to apply the IBM Workload Deployer interim fix6.
