-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2004.0069 -- Sun(sm) Alert Notification - Sun Alert ID: 57478 Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN - Patches Disable the Auditing Functionality on Basic Security Module (BSM) Enabled Systems 27 January 2004 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Basic Security Module (BSM) Publisher: Sun Microsystems Operating System: Solaris 9 Impact: Reduced Security Original Bulletin: http://sunsolve.sun.com/pub-cgi/retrieve.pl?doc=fsalert%2F57478 - --------------------------BEGIN INCLUDED TEXT-------------------- DOCUMENT ID: 57478 SYNOPSIS: Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN - Patches Disable the Auditing Functionality on Basic Security Module (BSM) Enabled Systems DETAIL DESCRIPTION: Sun(sm) Alert Notification * Sun Alert ID: 57478 * Synopsis: Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN - Patches Disable the Auditing Functionality on Basic Security Module (BSM) Enabled Systems * Category: Security * Product: Solaris * BugIDs: 4975802 *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 Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN and are no longer available on SunSolve. 2.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.
