   Solution Type: Sun Alert

   Solution  245806 :   A Buffer Overflow Security Vulnerability in the
   Solaris sadmind(1M) Daemon May Lead to Execution of Arbitrary Code
   Bug ID: 6710920

   Product

   Solaris 8 Operating System
   Solaris 9 Operating System

   Date of Workaround Release: 14-Nov-2008

   A Buffer Overflow Security Vulnerability in the Solaris sadmind(1M)
   Daemon May Lead to Execution of Arbitrary Code

   1. Impact

   A buffer overflow security vulnerability in the Solaris sadmind(1M)
   daemon may allow a local or remote unprivileged user to execute
   arbitrary code with root privileges.

   Sun acknowledges with thanks, Adriano Lima of RISE security for
   bringing this issue to our attention.

   This issue is described in the following documents:

   RISE-2008001 at http://risesecurity.org/advisories/RISE-2008001.txt
   CVE-2008-4556 at:

   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4556

   2. Contributing Factors

   This issue can occur in the following releases:
   SPARC Platform

     * Solaris 8 Operating System
     * Solaris 9 Operating System

   x86 Platform

     * Solaris 8 Operating System
     * Solaris 9 Operating System

   Note: Solaris 10 and OpenSolaris do not ship with sadmind(1M) and
   therefore are not affected by this issue.

   To determine if sadmind(1M) is enabled on the system, the following
   command can be run:

      $ grep sadmind /etc/inet/inetd.conf
      100232/10  tli  rpc/udp wait root /usr/sbin/sadmind  sadmind

   3. Symptoms

   There are no predictable symptoms that would indicate this issue has
   been exploited to execute arbitrary code.

   4. Workaround

   To work around this issue, sadmind(1M) can be disabled by doing the
   following:

   1. Edit the '/etc/inetd.conf' file as the root user to comment out the
   entry for sadmind(1M). This entry will then read as:

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

   2. Restart the inetd(1M) process to reread the newly modified
   '/etc/inetd.conf' file. This may be done using the following command:

   # /usr/bin/pkill -HUP inetd

   5. Resolution

   A final resolution is pending completion.
