   Solution Type: Sun Alert
   Solution  239728 :   A Security Vulnerability in picld(1M) May Allow a
   Denial of Service to System Monitoring and System Services          
   Bug ID: 6547926

   Product
   Solaris 8 Operating System
   Solaris 9 Operating System
   Solaris 10 Operating System
   OpenSolaris

   Date of Resolved Release: 30-Jul-2008

   SA Document Body
   A Security Vulnerability in picld(1M) May Allow a Denial of Service to 
   System Monitoring and System Services

   1. Impact
   Due to a security vulnerability in the Solaris Platform Information
   and Control Library daemon (picld(1M)), a local unprivileged user may
   be able to disable system monitoring and prevent system utilities
   (prtdiag(1M), prtpicl(1M), prtfru(1M)) from operating properly. This
   is a type of Denial of Service (DoS).
   2. Contributing Factors
   This can occur in the following releases:
   SPARC Platform:
     * Solaris 8 (10/00 or later) without patch 112169-07
     * Solaris 9 without patch 137400-01
     * Solaris 10 without patch 138068-01
     * OpenSolaris based upon builds snv_01 through snv_95

   x86 Platform:
     * Solaris 9 without patch 137401-01
     * Solaris 10 without patch 138069-01
     * OpenSolaris based upon builds snv_01 through snv_95

   Notes:
   1. Solaris 8 on the x86 platform is not impacted by this issue
   2. Only OpenSolaris installations including the affected binary below
   are impacted by this issue.

   /usr/lib/picl/picld

   3. OpenSolaris distributions may include additional bug fixes above
   and beyond the build from which it was derived. The base build can be
   derived as follows:

   $ uname -a
   SunOS  phys-node-1 5.11 snv_86 i86pc i386 i86pc

   3. Symptoms
   If this issue has been exploited to cause a Denial of Service,
   invocations of prtpicl(1M), prtfru(1M) and prtdiag(1M) will not run to
   completion and will not display information that is normally seen.
   4. Workaround
   There is no workaround that would prevent this issue from being
   exploited.
   If the issue has been exploited, it is possible to recover from the
   Denial of Service state by stopping and restarting picld(1M) by doing
   the following:
   For Solaris 10, issue the following command:
   # svcadm restart picl

   For Solaris 9 and 8, issue the following commands:
   # /etc/init.d/picld stop
   # /etc/init.d/picld start

   5. Resolution
   This issue is addressed in the following releases:
   SPARC Platform:
     * Solaris 8 with patch 112169-07 or later
     * Solaris 9 with patch 137400-01 or later
     * Solaris 10 with patch 138068-01 or later
     * OpenSolaris based upon builds snv_96 or later

   x86 Platform:
     * Solaris 9 with patch 137401-01 or later
     * Solaris 10 with patch 138069-01 or later
     * OpenSolaris based upon builds snv_96 or later
