ISS Security Update
November 16th, 1998

This update contains updated patch information for the ISS Security
Advisories "Hidden community string in SNMP implementation" and "BMC
PATROL File Creation Vulnerability"  released on November 2, 1998.

Hidden community string in SNMP implementation

Synopsis:

Internet Security System (ISS) X-Force has discovered a serious
vulnerability in Sun Microsystems(r) Solstice(tm) Enterprise Agent(tm)
and the Solaris operating system.  This SNMP hidden community string is
hard coded into the binary and can not be configured nor is it in the
configuration files.  The hidden Sun SNMP community word is not the same
as the hidden HP SNMP community string.  This vulnerability allows
attackers to execute arbitrary commands with root privileges, manipulate
system parameters, and kill processes.

To determine if you are vulnerable:

Run pkginfo to determine the revision of SEA you are running on your
system.  If you are running SEA 1.0 or 1.0.1 on Solaris 2.4 or 2.5,
disable the agents or upgrade your operating system.  If you are running
2.5.1 or higher you may upgrade to SEA 1.0.3.

SEA 1.0 and 1.0.1 agents will display:

  % pkginfo SUNWmibii
        system      SUNWmibii      Solstice Enterprise Agent SNMP daemon

For SEA 1.0.2:

        % pkginfo SUNWmibii
        system      SUNWmibii      Solstice Enterprise Agents 1.0.2 SNMP daemon

Updated Fix Information:

The patch information initially provided in the November 2nd advisory was
incorrect.  Sun Microsystems advises all its Solaris 2.6, 2.6_x86. 2.5.1,
and 2.5.1_x86 customers to upgrade to Solstice Enterprise Agents
version1.0.3.  This version is available at
http://www.sun.com/solstice/products/ent.agents. Many system
administrators have no need for host-based SNMP agents. Administrators can
temporarily disable the SNMP daemons by executing the following commands
as root:

# /etc/init.d/init.snmpdx stop
# mv /etc/rc3.d/S76snmpdx /etc/rc3.d/DISABLED_S76snmpdx

BMC PATROL File Creation Vulnerability

Synopsis:

Internet Security Systems (ISS) X-Force has discovered a vulnerability in
BMC Software PATROL(r) network management software.  PATROL contains a
vulnerability that may allow local attackers to compromise root access.
The agent creates insecure temporary files that may lead to a symbolic
link attack.

Updated Fix Information:

BMC has made a patch available for this vulnerability.  BMC recommends
that its customers upgrade to PATROL Agent version 3.2.07, released
September 21, 1998.
