Vulnerability Details CVE-ID: CVE-2014-3065 DESCRIPTION: IBM Java SDK contains a vulnerability in which the default configuration for the shared classes feature potentially allows arbitrary code to be injected into the shared classes cache. This code subsequently can be executed by other local users. CVSS Base Score: 6 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93629 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:L/AC:H/Au:S/C:C/I:C/A:C) CVE-ID: CVE-2014-3566 DESCRIPTION: SSLv3 is vulnerable to Padding Oracle On Downgraded Legacy Encryption (POODLE) attacks. A man-in-the-middle attack could allow a remote user to get protected information. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N CVEID: CVE-2014-6457 DESCRIPTION: An unspecified vulnerability related to the JSSE component has partial confidentiality impact, partial integrity impact, and no availability impact. CVSS Base Score: 4 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97148 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:N) CVEID: CVE-2014-6512 DESCRIPTION: An unspecified vulnerability related to the Libraries component has no confidentiality impact, partial integrity impact, and no availability impact. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97147 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) Affected Products and Versions TPF Toolkit 4.2.x Remediation/Fixes Product VRMF APAR Remediation/First Fix TPF Toolkit 4.2.x JR51692 Install IBM Installation Manager 1.8, which does not use the SSLv3 protocol. IBM Installation Manager 1.8 is required on any machine that you install a TPF Toolkit interim fix on. Download IBM Installation Manager 1.8 from http://www-01.ibm.com/support/docview.wss?uid=swg24037640 Apply Interim Fix 4.2.2 by using IBM Installation Manager. Update the Java installation on your z/OS or Linux on System z (or both) systems that the TPF Toolkit connects to. Download the latest version of Java from http://www.ibm.com/developerworks/java/jdk/ Workarounds and Mitigations CVE-2014-3065: Instead of using the default cache directory, you can specify a cache directory that has limited permissions by using the cacheDir and cacheDirPerm options. If only a particular user has write access to the directory, no other users can modify the shared cache. To use a different cache directory, update the server file in the dstore host installation directory (for example, bin/server.linux on Linux on System z) to replace the –Xshareclasses parameter statement as follows, where path is the shared directory path of the new shared cache with limited permission: - -Xshareclasses:cacheDir=/path,cacheDirPerm=0700,name=RSE%g,groupAccess,nonfatal There is no known work around or mitigation for the other security issues; apply the fixes specified in the Remediation/Fixes section.
