The information in this Security bulletin should be acted upon as soon as possible. INITIAL RELEASE: 05 May 2004 POTENTIAL SECURITY IMPACT: Remote Denial of Service (DoS) SOURCE: HEWLETT-PACKARD COMPANY HP Software Security Response Team REFERENCES: CAN 2004-079, CAN-2004-0112 VULNERABILITY SUMMARY: A potential security vulnerability has been identified with Management Agents using OpenSSL and SSL/TLS which could be exploited remotely to create a denial of service (DoS) in HP WBEM Services on HP-UX and RedHat Enterprise Linux (RHEL). SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed. HP9000 Servers running HP-UX release B.11.00, B.11.11 and B.11.23 with versions of the following products are affected: - - HP WBEM Services for HP-UX, A.01.05.08 or earlier (B8465BA). Version A.01.05.08 of this product includes OpenSSL 0.9.6k. - - HP WBEM Services for HP-UX, A.02.00.00 (B8465BA). This product includes OpenSSL 0.9.6k. RedHat Enterprise Linux, RHEL AS 2.1 with the following HP product numbers/versions are affected: - - HP WBEM Services for Linux, A.02.00.01 BACKGROUND: The Common Vulnerabilities and Exposures project has identified potential vulnerabilities in OpenSSL (CAN-2004-079, CAN-2004-0112). 1. The do_change_cipher_spec function in OpenSSL allows remote attackers to cause a denial of service via a crafted SSL/TLS handshake that triggers a null dereference. http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0079 2. The SSL/TLS handshaking, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service via a crafted SSL/TLS handshake that causes an out-of-bounds read. http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0112 It affects the following HP product numbers/versions on HP-UX releases B.11.00, B.11.11, and B.11.23: - HP WBEM Services for HP-UX, A.01.05.08 or earlier (B8465BA) - HP WBEM Services for HP-UX, A.02.00.00 (B8465BA) It also affects the following HP product numbers/versions on RHEL AS 2.1: - HP WBEM Services for Linux, A.02.00.01 AFFECTED VERSIONS The following is a list of affected filesets or patches and fix information. On HP-UX, to determine if a system has an affected version, search the output of "swlist -a revision -l fileset" for an affected fileset or patch, then determine if a fixed revision or applicable patch is installed. HP-UX B.11.00 HP-UX B.11.11 HP-UX B.11.23 ============ WBEMServices.WBEM-CORE HP WBEM Services action: install revision A.01.05.09 or subsequent WBEMServices.WBEM-CORE HP WBEM Services action: install revision A.02.00.02 or subsequent END AFFECTED VERSIONS On Linux, to determine if a system has an affected version, search the output of "rpm -qa | grep wbem" for an affected fileset or patch, then determine if a fixed revision or applicable patch is installed. hp.com-wbem-2.0.1-rhas2_1 RESOLUTION: The OpenSSL group has released patches to fix the vulnerabilities in OpenSSL 0.9.7d. For customers using HP WBEM Services, HP has incorporated OpenSSL 0.9.7d in the following product: - - HP WBEM Services for HP-UX, A.01.05.09 or later - - HP WBEM Services for HP-UX, A.02.00.02 or later - - HP WBEM Services for Linux, A.02.00.02 or later System: hprc.external.hp.com (192.170.19.51) Login: wbem123 Password: wbem123 FTP Access: ftp://wbem123:wbem123@hprc.external.hp.com/ or: ftp://wbem123:wbem123@192.170.19.51/ or: ftp://hprc.external.hp.com Note: There is an ftp defect in IE5 that may result in a browser hang. To work around this: - - Select Tools -> Internet Options -> Advanced - - Un-check the option: [ ] Enable folder view for FTP sites ================================================== To fix the problem: 1. Determine the affected version. 2. Download and verify the cksum or md5 sum. 3. Install the appropriate HP WBEM Services depot or rpm. cksum: 3788678079 131405 B8465-90020.pdf 2299865214 134962 B8465-90021.pdf 1197831072 6060093 B8465BA_A.01.05.09_HP-UX_B.11.00_32+64.depot.gz 443376171 6059783 B8465BA_A.01.05.09_HP-UX_B.11.11_32+64.depot.gz 113794493 16947990 B8465BA_A.01.05.09_HP-UX_B.11.23_IA.depot.gz 1574426678 8734861 B8465BA_A.02.00.02_HP-UX_B.11.11_32+64.depot.gz 1543241775 5628442 hp.com-wbem-2.0.2-rhas2_1.ia64.rpm.gz 685075578 5438885 hp.com-wbem-2.0.2-rhas2_1.i386.rpm.gz MD5: C3300B25F7A62E3442156FBF57FA97FB B8465-90020.pdf C2EEFBD4DB4AE2C1E242B5F94112A5DF B8465-90021.pdf de76ca4d30641dc7414a2d1a8d630e62 B8465BA_A.01.05.09_HP-UX_B.11.00_32+64.depot.gz a87b0345ba7edd258c4b008c37e1550f B8465BA_A.01.05.09_HP-UX_B.11.11_32+64.depot.gz 204bdd55be8cf97c6d9f4ea879383ce2 B8465BA_A.01.05.09_HP-UX_B.11.23_IA.depot.gz e6c036b0e9b8485265521582be893edc B8465BA_A.02.00.02_HP-UX_B.11.11_32+64.depot.gz 529e83d49485a716bae31ce214aa4976 hp.com-wbem-2.0.2-rhas2_1.ia64.rpm.gz 4a825a3c83597de771eb536ae8821980 hp.com-wbem-2.0.2-rhas2_1.i386.rpm.gz Check for HP WBEM Services Installation - -------------------------------------------- To determine if HP WBEM Services is installed on your system, on HP-UX, use the Software Distributor's swlist command.
