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SYNOPSIS: Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN -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* Synopsis: Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN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Solaris 9 patches 114332-08 and 114929-06 are WITHDRAWN and are no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.
