OpenSSL is used by IBM MessageSight. IBM MessageSight has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2014-3569 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the failure to properly handle attempts to use unsupported protocols by the ssl23_get_client_hello function in s23_srvr.c. A remote attacker could exploit this vulnerability using an unexpected handshake to trigger a NULL pointer dereference and cause the daemon to crash. CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99706 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-0205 DESCRIPTION: OpenSSL could allow a remote authenticated attacker to bypass security restrictions, caused by the acceptance of a DH certificate for client authentication without verification. An attacker could exploit this vulnerability to authenticate without the use of a private key. CVSS Base Score: 2.1 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99708 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:S/C:N/I:P/A:N) Affected Products and Versions IBM MessageSight V1.1 and V1.2 Remediation/Fixes Product VRMF APAR Remediation / First Fix IBM MessageSight 1.1 IT07319 1.1.0.1-IBM.IMA-IFIT07005 IBM MessageSight 1.2 IT07319 1.2.0.0-IBM-IMA-IFIT07005 Get Notified about Future Security Bulletins Subscribe to My Notifications to be notified of important product support alerts like this.
