   Solution Type: Sun Alert
   Solution  261088 :   Multiple Security Vulnerabilities in Common UNIX
   Printing System (CUPS) May Allow a Remote User to Execute Arbitrary
   Code
   Bug ID: 6765712

   Product
   OpenSolaris

   Date of Resolved Release: 10-Jun-2009

   SA Document Body
   Multiple Security Vulnerabilities in Common UNIX Printing System (CUPS)
   May Allow a Remote User to Execute Arbitrary Code

   1. Impact
   The Common UNIX Printing System (CUPS) as shipped with OpenSolaris is
   impacted by multiple security vulnerabilities affecting the
   "imagetops", "texttops" and "hpgltops" filters. These vulnerabilities
   may allow a local or remote unprivileged user to execute arbitrary
   code with the privileges of the CUPS service (which usually runs as
   root).
   These issues are described in the following documents:

   CVE-2008-3640 at

   http://www.cups.org/str.php?L2911

   2. Contributing Factors
   These issues can occur in the following releases:
   SPARC Platform:
     * OpenSolaris based upon builds snv_87 through snv_102

   x86 Platform:
     * OpenSolaris based upon builds snv_87 through snv_102

   Notes:
   1. Solaris 8, 9, and 10 are not impacted by these issues.
   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 -v
   snv_101

   2. These vulnerabilities only affect systems which are configured to
   use the CUPS software. This can be determined by checking the status
   of the appropriate SMF (smf(5)) service as in the following example:
   % svcs application/cups/in-lpd
   STATE          STIME    FMRI
   enabled        Mar_19   svc:/application/cups/in-lpd:default

   3. A system is only vulnerable to a remote user while sharing a
   printer(s) on the network. To determine if a printer is being network
   shared, the following command can be run:
   # grep Listen /etc/cups/cupsd.conf
   Listen localhost:631
   Listen /var/run/cups/cups.sock

   In the case above, it is listening only on the local interfaces.
   3. Symptoms
   There are no predictable symptoms that would indicate the described
   issues have been exploited.

   4. Workaround
   There is no workaround for these issues. Please see the "Resolution"
   section below.

   5. Resolution
   These issues are addressed in the following releases:
   SPARC Platform:
     * OpenSolaris based upon builds snv_103 or later

   x86 Platform:
     * OpenSolaris based upon builds snv_103 or later
