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.
