To insure system integrity, the patches should be ASSESSMENT: applied as soon as possible. ______________________________________________________________________________ [ Start Hewlett-Packard Advisories ] 1) snmp Document ID: HPSBUX9811-088 Date Loaded: 19981215 Title: Security Vulnerability with snmp - ------------------------------------------------------------------------- **REVISED 01** HEWLETT-PACKARD SECURITY BULLETIN: #00088, 30 November 1998 Last revised: 16 December 1998 - ------------------------------------------------------------------------- The information in the following Security Bulletin should be acted upon as soon as possible. Hewlett-Packard Company will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Bulletin as soon as possible. - ------------------------------------------------------------------------- PROBLEM: A SNMP community string in HP OpenView allow access to certain SNMP variables. PLATFORM: HP 9000 series 700/800. DAMAGE: May reduce manageability of affected HP-UX systems. SOLUTION: **REVISED 01** Install the patches listed below. AVAILABILITY: All patches are available now. CHANGE SUMMARY: A VirtualVault (VVOS 10.24) patch is available. - ------------------------------------------------------------------------- I. A. Background Reference: ISS X-force SNMP community resource notice, dated November 2nd, 1998. A SNMP community string exists in HP OpenView SNMP agent implementations allowing access to certain SNMP variables. This may result in limited manageability of affected HP-UX systems. The system remains operational but will be unable to respond to some queries from a management server. This problem is not an OpenView-specific problem, but OpenView can be affected when communicating with systems that have an affected agent. This HP OpenView Emanate SNMP Agent has two revisions currently supported, release 2.X and 14.X. HP recommends upgrading to the 14.X release and applying the patch to circumvent this vulnerability. B. Fixing the problem **REVISED 01** The defect is now fixed such that an unauthorized user can not use this mechanism. Please install the applicable patch: Emanate 14.2 version on HP-UX revision 11.00: PHSS_16846 Emanate 14.2 version on HP-UX revision 10.20: PHSS_16845 - ---->>>>Emanate 14.2 version on VVOS revision 10.24: PHSS_17083 Emanate 14.0 version on HP-UX revision 10.0X, 10.10: PHSS_16800 Emanate 14.0 version on HP-UX revision 9.X: PHSS_16799 Solaris 2.3 and 2.4 OpenView Emanate14.0 agent: PSOV_02190 Solaris 2.5.1 and 2.6 OpenView Emanate14.2 agent: PSOV_02191 The Solaris agent patches are available from: http://ovweb.external.hp.com:80/cpe/patches/emanate/14.x/sparc_2.X.html CAUTION: Installing any earlier HP OV Emanate patch, or reinstalling HP OpenView Network Node Manager (NNM) will reverse the protective effect of the patches listed above. Reinstallation of the above referenced patch will then be necessary. This means that if a system administrator deinstalls one of the earlier patches after installing the security patch, they will overwrite the security fixes with older software. The Solaris, HP-UX 9.X, and HP-UX 10.X patches are _NOT_ cumulative. The HP-UX 11.X patch is, however, cumulative (one that supersedes), and will not be affected in this manner. - --->>> Due to the security features on the VirtualVault system using VVOS - --->>> 10.24, the system is not vulnerable to the stated access from the - --->>> OUTSIDE or Internet. The vulnerability only exists on the INSIDE - --->>> or internal network. C.

Hewlett-Packard Company will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Bulletin as soon as possible. - ------------------------------------------------------------------------- PROBLEM: sendmail releases are vulnerable to mail spamming PLATFORM: HP 9000 series 700/800. DAMAGE: Remote users can compromise system integrity. SOLUTION: Apply the patches below. AVAILABILITY: All patches are available now. - ------------------------------------------------------------------------- I. A. Background Some important features provided by 8.8.6 includes a new group of rulesets to avoid mail "spamming" (i.e., sending of unsolicited mail to large number of users) and to prevent mail "spammers" from using your host as a mail relay point. Sendmail 8.8.6 provides four new named rulesets which can be used to check and reject abusive mail messages. Patches are available from the Electronic Support Center (ESC) patch hub for HP-UX 10.20, 10.30, and 11.0. An upgrade is available for HP-UX 10.00, 10.01, and 10.10. Hewlett-Packard recommends installing sendmail 8.8.6 for HP-UX 10.00, 10.01, and 10.10 as an optional version upgrade. This upgrade is not available from the Electronic Support Center (ESC) patch hub, but from: http://www.software.hp.com/software/HPsoftware/Sendmail/index.html There are numerous new configuration options available and various issues involved in upgrading to Sendmail 8.8.6. The URL above provides additional information regarding the impact of the upgrade. B. Fixing the problem - For the HP-UX releases listed below, an official patch is available. For HP-UX release 10.20: PHNE_12836, HP-UX release 10.30: PHNE_12866, HP-UX release 11.00: PHNE_15509. NOTE: The VirtualVault product (HP-UX 10.24) is not affected. C.
