1.  Bulletins Topics

    Sun announces the release of patches for Solaris(tm) 7, 2.6, 2.5.1,
    2.5, 2.4, and 2.3 (SunOS(tm) 5.7, 5.6, 5.5.1, 5.5, 5.4 and 5.3), which
    relate to a vulnerability with sadmind.

    Sun recommends that you install the patches listed in section 4
    immediately on systems running SunOS 5.7, 5.6, 5.5.1, and 5.5 and
    on systems with Solstice AdminSuite (AdminSuite) installed. If you have
    installed a version of AdminSuite prior to version 2.3, please upgrade
    to AdminSuite 2.3 before installing the AdminSuite patches listed in
    section 4.

    Sun also recommends that you:

    - disable sadmind if you do not use it by commenting the
      following line in /etc/inetd.conf:

        100232/10 tli rpc/udp wait root /usr/sbin/sadmind sadmind

    - set the security level used to authenticate requests to STRONG
      as follows, if you use sadmind:

        100232/10 tli rpc/udp wait root /usr/sbin/sadmind sadmind -S 2

      The above changes to /etc/inetd.conf will take effect after inetd
      receives a hang-up signal.

2.  Who is Affected
        
    Vulnerable:     SunOS 5.7, 5.7_x86, 5.6, 5.6_x86, 5.5.1, 5.5.1_x86,
                              5.5, 5.5_x86, and
                              5.4, 5.4_x86, and 5.3 with AdminSuite installed

    Not vulnerable: All other supported versions of SunOS.

3.  Understanding the Vulnerability

    The sadmind program is installed by default on SunOS 5.7, 5.6, 5.5.1,
    and 5.5. In SunOS 5.4 and 5.3, sadmind may be installed if the
    Solstice AdminSuite packages are installed. The sadmind program
    is installed in /usr/sbin. The program can be used to perform
    distributed system administration operations remotely. A buffer overflow
    vulnerability has been discovered in sadmind which may be exploited by
    a remote attacker to execute arbitrary instructions and gain root access.
