Involving the Parsing of Labeled Packets May Result in Denial of Service (DoS)  

Bug ID

Product
Solaris 10 Operating System
OpenSolaris

Date of Resolved Release
29-Jul-2009

SA Document Body
A remote user may be able to panic systems configured with Solaris Trusted 
Extensions ... (see below)

1. Impact

A security vulnerability in Solaris Trusted Extensions when parsing labeled 
packets may allow a remote privileged user to be able to panic the system 
which is a type of Denial of Service (DoS).

2. Contributing Factors

This issue can occur on the following releases:

SPARC platform

    * Solaris 10 Update 3 (11/06) or later without patch 141414-06
    * OpenSolaris based upon builds snv_37 through snv_120

x86 Platform

    * Solaris 10 Update 3 (11/06) or later without patch 141415-06
    * OpenSolaris based upon builds snv_37 through snv_120

Notes: Solaris 8 and 9 are not impacted by this issue.

This issue only impacts systems which have Solaris Trusted Extensions 
installed and running. To determine if Trusted Extensions is installed and 
running on a host, execute the following command in the global zone:

         $ svcs labeld
         online         16:19:20 svc:/system/labeld:default

If Trusted Extensions is configured and running, the labeld service will have 
an instance in the online state.

3. Symptoms

If this issue occurs, the system may panic with a stack trace similar to the 
following:

     unix:real_mode_end+72c1 ()
     unix:trap+5e6 ()
     unix:_cmntrap+140 ()
     ip:tsol_get_option+20 ()
     ip:ip_input+45b ()
     dls:i_dls_link_rx+32e ()
     mac:mac_rx+71 ()
     bge:bge_receive+98 ()
     bge:bge_intr+f6 ()

4. Workaround
