A security vulnerability in the OpenSolaris hald(1M) daemon ...

1. Impact

A security vulnerability in the OpenSolaris hald(1M) daemon may result in it not writing audit
records when the system is configured to do so.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• OpenSolaris based upon builds snv_51 through snv_130
  

x86 Platform

• OpenSolaris based upon builds snv_51 through snv_130
  

Note 1: This issue only affects systems which have Solaris Auditing
enabled (see bsmconv(1M)). To determine if a system has Solaris
Auditing enabled the grep(1) command can be used to search the
'/etc/system' file for a reference to the c2audit kernel module as in
the following example:

            $ grep c2audit /etc/system
            set c2audit:audit_load = 1 

Note 2: Solaris 8, 9 and 10 do not include the hald daemon and are therefore
not impacted by this issue.

Note 3: This issue only affects hosts which have the hald daemon enabled.
To determine if hald daemon is enabled in system, the following command can be used:

    $ svcs hal
    STATE STIME FMRI
    online 10:08:43 svc:/system/hal:default

Note 4: OpenSolaris distributions may include additional bug fixes
above and beyond the build from which it was derived. To determine the
base build of OpenSolaris, the following command can be used:

            $ uname -v
            snv_86

3. Symptoms

When this issue occurs, audit records related to the hald daemon are
not written to the auditing log. If the "priv_debug" parameter is set
in the /etc/system file at boot time, then a message similar to the
following may appear in the messages file:

  	NOTICE: hald[100323]: missing privilege "proc_audit" (euid = 0,
 	syscall = 186) needed at auditctl+0x58

4. Workaround

There is no workaround for this issue. Please see Resolution section below.

5. Resolution

This issue is addressed in the following releases:

SPARC Platform

• OpenSolaris based upon builds snv_131 or later

x86 Platform

• OpenSolaris based upon builds snv_131 or later
