===================================================================== CERT-Renater Note d'Information No. 2008/VULN255 _____________________________________________________________________ DATE : 27/06/2008 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Solaris running snmpXdmid. ====================================================================== http://sunsolve.sun.com/search/document.do?assetkey=1-66-237985-1 ______________________________________________________________________ Solution Type Sun Alert Solution 237985 : A Security Vulnerability in the Solaris snmpXdmid(1M) may lead to a Denial of Service (DoS) condition Bug ID 6450410 Product Solaris 8 Operating System, Solaris 9 Operating System, Solaris 10 Operating System Date of Resolved Release 26-Jun-2008 SA Document Body A Security Vulnerability in the Solaris snmpXdmid(1M) may lead to a Denial of Service (DoS) condition 1. Impact A security vulnerability in the Sun Solstice Enterprise SNMP-DMI mapper subagent daemon (snmpXdmid(1M)) running on Solaris may allow a local or remote unprivileged user to kill the daemon process by sending malformed packets. This is a type of Denial of Service (DoS). Sun acknowledges, with thanks, IBM Internet Security Systems X-Force (http://xforce.iss.net) for bringing this issue to our attention. 2. Contributing Factors This issue can occur in the following releases: SPARC Platform: * Solaris 8 without patch 108869-35 * Solaris 9 without patch 137402-01 * Solaris 10 without patch 128415-01 x86 Platform: * Solaris 8 without patch 108870-35 * Solaris 9 without patch 137403-01 * Solaris 10 without patch 128416-01 Note: Only systems that have the SUNWsadmi package installed and have DMI service enabled are impacted by this issue. To determine if the package is installed on the system, the following command can be run: $ pkginfo SUNWsadmi system Solstice Enterprise Agents 1.0.3 Desktop Management Interface To determine if snmpXdmi is enabled on a system, the following command can be run: On Solaris 10: $ svcs svc:/application/management/dmi:default On Solaris 8 and 9: $ ps -aef | grep snmpXdmid root 1658 1 0 15:47:05 ? 0:00 /usr/lib/dmi/snmpXdmid -s The above output indicates that the SUNWsadmi package is installed on the system and the DMI service is enabled. 3. Symptoms Should the described issue occur, snmpXdmid will core dump. The pstack output of the core file will appear similar to the following: core 'core' of 362: /usr/lib/dmi/snmpXdmid -s ----------------- lwp# 2 / thread# 2 -------------------- 00025cd8 handle_CompLangGrpIndication (7, fef7bde8, 44448, fef7bde8, b0be0, 20) ++ dc 00024de0 _dmicomponentadded_0x1_svc (fef7bde8, 49bd0, fef7bde8, fffffff8, 0, +fef7be11) + 8 000250d0 dmi2_client_0x1 (49bd0, b3e68, 1, 0, 74637000, 74637000) + 1dc ff1d15ec _svc_prog_dispatch (b3e68, b0c58, 49bd0, 4ede4, ff1d12e4, 0) + 180 ff1d1398 svc_getreq_common (8, 0, 8, 4ede4, ff1d1240, bab68) + d4 ff1d12a4 svc_getreq_poll (bab68, 1, ffffffff, 4, 0, bab68) + c4 00024da0 waitForIndication (0, 0, 0, 0, 0, 0) + 98 ff295c94 _lwp_start (0, 0, 0, 0, 0, 0) ----------------- lwp# 1 / thread# 1 -------------------- ff099a00 _so_recvfrom (7, 480e0, 47790, 2, ff15ff4c, fffed4f8) + c 00018d08 main (0, 31f2c, 31f84, 47800, 0, 0) + 2ec 000189d8 _start (0, 0, 0, 0, 0, 0) + 108 4.
