        1. Impact
      </h2><p>
Local unprivileged users may be able to panic Solaris systems with Basic
Security Module (BSM) enabled causing a Denial of Service (DoS). This
issue can only occur on systems where BSM has been configured to audit
the Administrative audit class "ad" or the System-Wide Administration
audit class "as". </p><h2>
        2. Contributing Factors
      </h2><p>
        This issue can occur in the following releases:
      </p><p>
        <b>SPARC Platform</b>
      </p><ul>
        <li>
          Solaris 7 without patch <a href="http://sunsolve.sun.com/pub-cgi/findPatch.pl?patchId=106541&rev=33">106541-33</a>

        </li>
      </ul><p>
        <b>Note:</b>
This issue can only occur on systems with BSM configured to audit either
the Administrative audit class "ad" or the System-Wide Administration
audit class "as". </p><p>
        If a Solaris system has BSM enabled, the following line will be present in the "/etc/system" file:
      </p><pre>    $ <b>grep c2audit /etc/system</b>
    set c2audit:audit_load = 1                        </pre><p>
To determine if either the Administrative audit class or the System-Wide
Administration audit class is configured to be audited, the "flags"
line of the "/etc/security/audit_control" file will contain either "ad"
or "as": </p><pre>    # <b>egrep ^flags:.*a[sd] /etc/security/audit_control</b>
    flags:lo,ad                        </pre><h2>
        3. Symptoms
      </h2><p>
        The system panics with a stack trace similar to the following:
      </p><pre>    pcache_poll+0x98(0, 30005437bc8, 25, 2a100aebaec, 1, 20)
    poll+0x3e0(ffbfaa60, 1, 300053f7ef0, 1388, 0, 18)
    syscall_trap32+0xa8(ffbfaa60, 3, 1388, 0, 1388, 0)                        </pre></font><table width="100%" cellpadding="2" cellspacing="0" border="0"><tbody><tr bgcolor="#999999">
