Vulnerability Details CVE-ID: CVE-2014-0160 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0160 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the TLS/DTLS heartbeat functionality. An attacker could exploit this vulnerability to expose 64k of private memory and retrieve secret keys. This vulnerability can be remotely exploited, authentication is not required and the exploit is not complex. An exploit can affect the confidentially, but not integrity or availability. CVSS Base Score: 5.0 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92322 CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N) Warning: We strongly encourage you to take action as soon as possible as potential implications to your environment may be more serious than indicated by the CVSS score. Affected Products and Versions: OpenSSL version 1.0.1.500 and above in the following AIX/VIOS releases: AIX: 5.3, 6.1, 7.1 and VIOS 2.2.* Remediation/Fixes Product AIX 5.3, 6.1, 7.1 and VIOS 2.2.* VRMF OpenSSL version greater or equal to 1.0.1.500 APAR N/a Remediation/First Fix ftp://aix.software.ibm.com/aix/efixes/security/openssl_ifix7.tar (ifix: 0160_ifix.140409.epkg.Z) This ifix disables the OpenSSL heartbeat option by compiling with - -DOPENSSL_NO_HEARTBEATS. Note: AIX OpenSSL v0.9.8.xxxx and 12.9.8.xxxx are not vulnerable to this security vulnerability. After applying the fix, additional instructions are needed for CVE-2014-0160 1) Replace your SSL Certificates. You need to revoke existing SSL certificates and reissue new certificates. You need to be sure not to generate the new certificates using the old private key and create a new private key (ie using "openssl genrsa") and use that new private key to create the new certificate signing request (CSR). 2) Reset User Credentials Users of network facing applications protected by a vulnerable version of OpenSSL should be forced to reset their passwords and should revoke any authentication or session related cookies set prior to the time OpenSSL was upgraded and force the user to re-authenticate. Warning: Your environment may require additional fixes for other products, including non-IBM products. Please replace the SSL certificates and reset the user credentials after applying the necessary fixes to your environment.
