From agent99@sgi.com Fri Apr 26 03:33:40 2002 From: SGI Security Coordinator To: agent99@sgi.com Date: Wed, 24 Apr 2002 09:52:06 -0700 (PDT) Subject: IRIX hpsnmpd vulnerability [The following text is in the "iso-8859-1" character set] [Your display is set for the "US-ASCII" character set] [Some characters may be displayed incorrectly] -----BEGIN PGP SIGNED MESSAGE----- _____________________________________________________________________________ SGI Security Advisory Title: IRIX hpsnmpd vulnerability Number: 20020404-01-P Date: April 24, 2002 Reference: CERT CA-2002-03 Reference: CVE CAN-2002-0012 Reference: CVE CAN-2002-0013 ______________________________________________________________________________ - ----------------------- - --- Issue Specifics --- - ----------------------- It has been reported that the IRIX /usr/etc/hpsnmpd, when used with a public read-only community, can be made to dump core when running the publicly available "PROTOS Test-Suite: c06-snmpv1" regression tests, see: http://www.ee.oulu.fi/research/ouspg/protos/testing/c06/snmpv1/ SGI is also investigating other non-base products that may have an SNMP component. SGI has investigated the issues and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL vulnerable SGI systems. This will be corrected in a future release of the product. - -------------- - --- Impact --- - -------------- The hpsnmp daemon is not installed by default, it is part of the snmpd.sw.hp package and can be optionally installed. In order to check to see if this package is installed, run the following command: # versions | grep snmpd.sw.hp If the output of the above command looks like either of the following, then the daemon is installed and the system is vulnerable: I snmpd.sw.hp 03/14/2001 SNMP Sub-agent for HP-UX MIB 1.1.2 I snmpd.sw.hp 03/14/2001 SNMP Sub-agent for HP-UX MIB 1.1.3 If the installed version is 1.1.2, then you must first upgrade to version 1.1.3 and then you can install the patch. If the installed version is older than 1.1.2, it won't work on IRIX 6.5 and should be uninstalled. These vulnerabilities may be exploited by a remote user, and no local account is required. This issue was reported on CERTŪ Advisory CA-2002-03 Multiple Vulnerabilities in Many Implementations of the Simple Network Management Protocol (SNMP): http://www.cert.org/advisories/CA-2002-03.html The PROTOS vulnerability was assigned the following CVE: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0012 This PROTOS vulnerability was also assigned the following CVE: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2002-0013 - ---------------------------- - --- Temporary Workaround --- - ---------------------------- The only workaround for these problems is to uninstall the product using the following commands: # versions remove snmpd.sw.hp SGI recommends installing patch 4544 according to the listing below. - ---------------- - --- Solution --- - ---------------- SGI has provided a patch for these vulnerabilities. Our recommendation is to install the appropriate patch. OS Version Vulnerable?
