SA Document Body
Security Vulnerability in the System Management Agent (SMA) SNMP daemon
(snmpd(1M))
1. Impact
A security vulnerability in the System Management Agent (SMA) SNMP
daemon (snmpd(1M)) that ships with Solaris may allow a local or remote
unprivileged user to execute arbitrary code with the privileges of the
SNMP daemon, or crash the SNMP daemon, which is a type of Denial of
Service (DoS).
This issue is also described in the following document:
CVE-2008-2292 at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2292
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform:
* Solaris 10 without patch 120272-21
* OpenSolaris based upon builds snv_01 through snv_92
x86 Platform:
* Solaris 10 without patch 120273-23
* OpenSolaris based upon builds snv_01 through snv_92
Notes:
1. Solaris 8 and Solaris 9 do not ship with the Net-SNMP software and
therefore are not impacted by this issue.
2. The Solaris 10 patches which address this vulnerability do not
increment the version of Net-SNMP. The version of Net-SNMP supplied
with the patches will still be reported as 5.0.9.
3. This issue only affects systems which have the SUNWsmagt package
installed. To determine if the SUNWsmagt package is installed on the
system, the following command can be run:
$ pkginfo -l SUNWsmagt
PKGINST: SUNWsmagt
NAME: System Management Agent files and libraries
CATEGORY: system
VERSION: 1.0,REV=2005.01.08.05.16
4. Only OpenSolaris installations including the affected binary listed
below are affected by this issue:
/usr/sfw/lib/libnetsnmp.so.5.0.9
5. OpenSolaris distributions may include additional bug fixes above
and beyond the build from which it was derived. The base build can be
derived as follows:
$ uname -a
SunOS phys-node-1 5.11 snv_86 i86pc i386 i86pc
3. Symptoms
There are no predictable symptoms that would indicate that the above
issue is being exploited.
4. Workaround
To prevent this issue from occurring until the system is upgraded or a
patch can be applied, the SMA service can be disabled on a system by
running the following command as the root user on Solaris 10 and
OpenSolaris releases:
# svcadm disable svc:/application/management/sma:default
5. Resolution
SPARC Platform:
* Solaris 10 with patch 120272-21 or later
* OpenSolaris based upon builds snv_93 or later
x86 Platform:
* Solaris 10 with patch 120273-23 or later
* OpenSolaris based upon builds snv_93 or later.
