Security Vulnerability in the System Management Agent (SMA) SNMP daemon (snmpd(1M))


Release Phase

Bug Id

Solaris 10 Operating System

Date of Workaround Release

Date of Resolved Release

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:

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


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
NAME: System Management Agent files and libraries
CATEGORY: system
VERSION: 1.0,REV=2005.

4. Only OpenSolaris installations including the affected binary listed below are affected by this issue:


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.
