Impact Sun Java System Application Server, Web Server and Proxy Server make use of the Network Security Services (NSS) library and are impacted by a number of security vulnerabilities related to the SSL2 implementation in that library if SSL2 is enabled in these servers. These vulnerabilities may allow remote users to cause the server to exit unexpectedly, causing a denial of service (DoS) to the application, or to execute arbitrary code. These issues are also described in the following documents: * CVE-2007-0008 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0008 * CVE-2007-0009 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0009 * CERT VU#377812 at: http://www.kb.cert.org/vuls/id/377812 * CERT VU#592796 at: http://www.kb.cert.org/vuls/id/592796 Other Sun products make use of the NSS library. For information regarding the impact to other products, please see Sun Alert 102856 at: * http://sunsolve.sun.com/search/document.do?assetkey=1-26-102856 -1 2. Contributing Factors These issues can occur in the following releases: SPARC Platform * Sun Java System Application Server Enterprise Edition 8.1 2005 Q1 without (file-based) patch 119169-16 or (SVR4) patch 119166-24 * Sun Java System Application Server Platform Edition 8.1 2005 Q1 without (file-based) patch 119173-16 or (SVR4) patch 119166-24 * Sun Java System Web Server 6.1 * Sun Java System Web Server 7.0 * Sun Java System Web Proxy Server 4.0 without Service Pack 5 x86 Platform * Sun Java System Application Server Enterprise Edition 8.1 2005 Q1 without (file-based) patch 119170-16 or (SVR4) patch 119167-24 * Sun Java System Application Server Platform Edition 8.1 2005 Q1 without (file-based) patch 119174-16 or (SVR4) patch 119167-24 * Sun Java System Web Server 6.1 * Sun Java System Web Server 7.0 * Sun Java System Web Proxy Server 4.0 without Service Pack 5 Linux Platform * Sun Java System Application Server Enterprise Edition 8.1 2005 Q1 without (file-based) patch 119171-16 or RHEL2.1/RHEL3.0 (Pkg_patch) 119168-24 * Sun Java System Application Server Platform Edition 8.1 2005 Q1 without (file-based) patch 119175-16 or RHEL2.1/RHEL3.0 (Pkg_patch) 119168-24 * Sun Java System Web Server 6.1 * Sun Java System Web Server 7.0 * Sun Java System Web Proxy Server 4.0 without Service Pack 5 AIX Platform * Sun Java System Web Server 6.1 HP-UX Platform * Sun Java System Web Server 6.1 * Sun Java System Web Server 7.0 * Sun Java System Web Proxy Server 4.0 without Service Pack 5 Windows Platform * Sun Java System Application Server Enterprise Edition 8.1 2005 Q1 without (file-based) patch 119172-16 or (package based patch) 122848-09 * Sun Java System Application Server Platform Edition 8.1 2005 Q1 without (file-based) patch 119176-16 * Sun Java System Web Server 6.1 * Sun Java System Web Server 7.0 * Sun Java System Web Proxy Server 4.0 without Service Pack 5 To determine the version of Sun Java System Application Server on a system, the following command can be run: $ /bin/asadmin version --verbose (Where is the installation directory of the Application Server ) To determine the version of Sun Java System Web Server on a system, the following command can be run: $ /https-/start -version (Where is the installation directory of the Web Server and should be the actual host name on which the Web Server is installed) To determine the version of Sun Java System Web Proxy Server on a system, the following command can be run: $ /bin/ns-proxy -v (Where is the installation directory of the Web Proxy Server) Note: SSL v2 is disabled by default in the Sun Java System Application Server, Sun Java System Web Server, and Sun Java System Web Proxy Server. 3. Symptoms There are no reliable symptoms that would indicate the described issues have been exploited. 4. Relief/Workaround In order to work around these issues in products which use the NSS library, SSL v2 can be disabled. For example if SSL v2 has been enabled in the Sun Java System Application Server, Sun Java System Web Server, or Sun Java System Web Proxy Server then it can be disabled until patches can be applied. The exact procedure to disable SSL v2 for each of these Sun Java System products varies. See the respective product documentation at http://docs.sun.com for further details. 5.
