Security Bulletin: Vulnerabilities in OpenSSL affect IBM BladeCenter Advanced Management Module (CVE-2014-3513, CVE-2014-3567, CVE-2014-3568)

Vulnerability Details

Summary

OpenSSL vulnerabilities along with SSL 3 Fallback protection (TLS_FALLBACK_SCSV) were disclosed on October 15, 2014 by the OpenSSL Project. OpenSSL is used by IBM BladeCenter Advanced Management Module. IBM BladeCenter Advanced Management Module has addressed the applicable CVEs and included the SSL 3.0 Fallback protection (TLS_FALLBACK_SCSV) provided by OpenSSL.

Vulnerability Details:

CVE-ID: 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 current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

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 http://xforce.iss.net/xforce/xfdb/97036 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: 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 current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)
