Bulletins Topics Sun announces the release of patches for Solaris(tm) 8, 7, and 2.6 (SunOS(tm) 5.8, 5.7, and 5.6) which relate to a buffer overflow in snmpdx(1M). Sun recommends that you install the patches listed in section 4 immediately on systems running the Sun Solstice Enterprise Master Agent, snmpdx(1M), on SunOS 5.8, 5.7, and 5.6. 2. Who is Affected Vulnerable: SunOS 5.8, 5.8_x86, 5.7, 5.7_x86, 5.6, 5.6_x86 3. Understanding the Vulnerability The Sun Solstice Enterprise Master Agent, snmpdx, runs as a daemon process and listens to User Datagram Protocol (UDP) port 161 for SNMP request. The snmpdx daemon also opens another port to receive SNMP trap notifications from various subagents. These traps are forwarded to various managers, as determined by the configuration file. The snmpdx master agent runs as a daemon with root privileges on the system. The snmpdx daemon is started by default via the /etc/rc3.d/S76snmpdx script. A buffer overflow has been discovered in snmpdx which may be exploited by a local or a remote attacker to gain root access on the affected system. Any system that does not run the Sun Solstice Enterprise Master Agent, sndmpx, is not vulnerable to this issue. This issue was discovered by the Oulu University Secure Programming Group (OUSPG) who developed a PROTOS test suite for SNMPv1. Information regarding the PROTOS project is available here: http://www.ee.oulu.fi/research/ouspg/protos/ CERT Advisory CA-2002-03 is available from: http://www.cert.org/advisories/CA-2002-03.html 4. List of Patches The following patches are in the process of being propagated to the worldwide SunSolve sites and should be available in the very near future: OS Version Patch ID __________ _________ SunOS 5.8 108869-15 SunOS 5.8_x86 108870-15 SunOS 5.7 107709-18 SunOS 5.7_x86 107710-18 SunOS 5.6 106787-17 SunOS 5.6_x86 106872-17 _______________________________________________________________________________ Sun acknowledges with thanks, the Oulu University Secure Group (OUSPG), (http://www.ee.oulu.fi/research/ouspg/) for bringing this issue to our attention. _______________________________________________________________________________ APPENDICES A.
