Sun Microsystems, Inc. Security Bulletin

Bulletin Number:        #00178
Date:                         November 9, 1998
Cross-Ref:                ISS Security Advisory: Hidden community string in SNMP
                        implementation
Title:                        SNMP
________________________________________________________________________________

1. Background

    Solstice Enterprise Agents(tm) expands the scope of enterprise management
    by providing a comprehensive development and runtime environment
    enabling the creation of custom, extensible agents for device and
    system management for the Solaris(tm) operating environment. Solstice
    Enterprise Agents(SEA) supports both the Simple Network Management
    Protocol and DMI protocols.

    Simple Network Management Protocol(SNMP) was designed to allow the
    remote management of systems and devices on a network. SNMP relies on
    processes known as master agents and subagents. Upon invocation,
    agents read various configuration files and maintain Management
    Information Bases(MIBs). Access to information in the MIBs can be
    controlled by community strings. A default community string is present
    in the Sun SNMP subagent that may be exploited by remote attackers to
    modify system parameters or execute arbitrary commands with root
    privileges.

SEA was initially available as an unbundled product and later bundled
with Solaris 2.6 at version 1.0.1.

2. Recommendations

Sun recommends that sites running Solaris 2.6 and sites running SEA on
Solaris 2.5.1 upgrade the SEA software to SEA 1.0.3.

SEA 1.0.3 is bundled with Solaris 7. SEA 1.0.3 is available for Solaris
2.6, 2.6_x86, 2.5.1, and 2.5.1_x86 and may be downloaded from:

http://www.sun.com/solstice/products/ent.agents/

    Sun also recommends that sites running SEA 1.0 on Solaris 2.4 and 2.5
    either disable SEA (see section 3) or upgrade the operating system to
    Solaris 7 if possible. Sites upgrading to Solaris 2.5.1 or 2.6 may
    obtain SEA 1.0.3 from the URL listed above.

3. Workaround

Sun recommends that you disable SEA on vulnerable systems until
SEA 1.0.3 is installed.

    To determine if your system is using SEA, use pkginfo on one of the
    following SEA packages: SUNWmibii, SUNWsacom, SUNWsadmi, SUNWsasnm.
    For example, on SEA 1.0 and 1.0.1, a pkginfo on SUNWmibii will display
    as follows:

% pkginfo SUNWmibii
system SUNWmibii Solstice Enterprise Agent SNMP daemon

On SEA 1.0.2:

% pkginfo SUNWmibii
system SUNWmibii Solstice Enterprise Agents 1.0.2 SNMP daemon

To disable SEA, perform the following steps:

                    % su
                Password:
                # /etc/init.d/init.snmpdx stop
                # mv /etc/rc3.d/S76snmpdx /etc/rc3.d/DISABLED_S76snmpdx

Sun Microsystems, Inc. Security Bulletin

Bulletin Number:        #00180
Date:                         December 17, 1998
Cross-Ref:                CERT Advisory CA-98.05
Title:                        BIND
________________________________________________________________________________

1. Background

The Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS).

    CERT Advisory CA-98.05 describes three vulnerabilities in certain
    versions of BIND. The first vulnerability, Inverse Query Buffer Overrun,
    can be exploited by a remote attacker to gain root access to a DNS
    name server. The second vulnerability, Denial-of-Service Vulnerabilities,
    is concerned with buffer overflows that can be exploited to corrupt
    DNS record data or crash the DNS server. SunOS(tm) and Solaris(tm) are
    not vulnerable to third vulnerability described in the CERT advisory.
    For more information about the vulnerabilities, please see the
    CERT advisory at:

http://www.cert.org/ftp/cert_advisories/CA-98.05.bind_problems

    A vulnerability has also been discovered in SunOS and Solaris's
    implementation of BIND with their use of temporary files. This vulnerability
    can be exploited to overwrite arbitrary files.

2. Affected Supported Versions

Solaris(tm) versions: 2.6, 2.6_x86, 2.5.1, 2.5.1_x86, 2.5, 2.5_x86,
2.4, 2.4_x86 and 2.3

SunOS(tm) versions: 4.1.4 and 4.1.3_U1

3. Recommendations

Sun recommends that you install the respective patches immediately on
vulnerable systems including both DNS clients and servers.
