Sun(sm) Alert Notification
     * Sun Alert ID: 102060
     * Synopsis: Security Vulnerabilities in the traceroute(1M) Utility
       may Allow Elevated Privileges
     * Category: Security
     * Product: Solaris 10 Operating System
     * BugIDs: 6290623, 6290611
     * Avoidance: Patch, Workaround
     * State: Resolved
     * Date Released: 23-Nov-2005
     * Date Closed: 23-Nov-2005
     * Date Modified: 

1. Impact

   Multiple security vulnerabilities in the traceroute(1M) utility may
   allow an unauthorized local user the ability to execute arbitrary code
   with elevated privileges. The traceroute(1M) utility in Solaris 10 is
   privilege aware and thus the only additional privilege available is
   PRIV_NET_RAWACCESS (see privileges(5)). This limits the impact by only
   allowing access to the network layer.

   These issues are described in the following document:
     * http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2071

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform
     * Solaris 10 without patch 121012-01

   x86 Platform
     * Solaris 10 without patch 121013-01

   Note: Solaris 8 and Solaris 9 are not affected by this issue.

3. Symptoms

   There are no reliable symptoms that would indicate the described issue
   has been exploited. 

4. Relief/Workaround

   To work around the described issue, the "set user ID bit" (suid) may
   be removed from the traceroute(1M) binary (or the binary may be
   removed altogether), which will render it unusable to non-root users.

   To remove the suid bit, run the following command as root user:
    # chmod u-s /usr/sbin/traceroute


5. Resolution

   This issue is addressed in the following releases:

   SPARC Platform
     * Solaris 10 with patch 121012-01 or later

   x86 Platform
     * Solaris 10 with patch 121013-01 or later
