   DOCUMENT ID: 57478
   SYNOPSIS: Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN -
   Patches Disable the Auditing Functionality on Basic Security Module
   (BSM) Enabled Systems
   DETAIL DESCRIPTION:
   
Sun(sm) Alert Notification

     * Sun Alert ID: 57478
     * Synopsis: Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN
       - Patches Disable the Auditing Functionality on Basic Security
       Module (BSM) Enabled Systems
     * Category: Security
     * Product: Solaris
     * BugIDs: 4975802
     * Avoidance: Workaround
     * State: Engineering Complete
     * Date Released: 22-Jan-2004
     * Date Closed:
     * Date Modified:
       
1. Impact

   Solaris 9 systems with Basic Security Module (BSM) enabled (see
   bsmconv(1M)) and either patch 114332-08 for SPARC or 114929-06 for x86
   installed will not have BSM/auditing functionality present after the
   system is rebooted.
   
   Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN and are no
   longer available on SunSolve.
   
2. Contributing Factors

   This issue can occur in the following releases:
   
   SPARC Platform
     * Solaris 9 with patch 114332-08
       
   x86 Platform
     * Solaris 9 with patch 114929-06
       
   Notes:
    1. Solaris 2.6 will not be evaluated regarding the potential impact
       of the issue described in this Sun Alert.
    2. Solaris 7 and 8 are not affected by this issue.
    3. This issue only affects systems which have BSM (see bsmconv(1M))
       enabled.
       
   A system has BSM enabled if the following "c2audit" line is present in
   the "/etc/system" file:
    $ grep c2audit /etc/system
    set c2audit:audit_load = 1                              

3. Symptoms

   When the system is rebooted the following messages will be displayed
   on the console during boot:
    /etc/rc2.d/S99audit: /etc/security/audit_startup: cannot execute           
                   

   Solaris 9 BSM enabled systems which have been rebooted will find that
   BSM/auditing has not been enabled correctly on the system. The
   auditconfig(1M) command will report the discrepancy, as in this
   example:
    # auditconfig -chkaconf
    non-attributable event mismatch audit_control(lo) kernel(no)               
               
    # auditconfig -chkconf
    AUE_EXIT(1): CLASS MISMATCH: runtime class (no) != configured class (pc)
    AUE_FORK(2): CLASS MISMATCH: runtime class (no) != configured class (pc)
    AUE_OPEN(3): CLASS MISMATCH: runtime class (no) != configured class (fa)
    AUE_CREAT(4): CLASS MISMATCH: runtime class (no) != configured class (fc)
    AUE_LINK(5): CLASS MISMATCH: runtime class (no) != configured class (fc)
    ...                              

   SOLUTION SUMMARY:
   
4. Relief/Workaround

   To work around the described issue, BSM/auditing functionality can be
   restored by running the following commands executed as the "root"
   user:
    # /usr/bin/chmod 0744 /etc/security/audit_startup
    # /etc/init.d/audit stop
    # /etc/init.d/audit start                              

   This will restore BSM/auditing functionality on BSM enabled systems.
   
5. Resolution

   A final resolution is pending completion.
