   A Security Vulnerability in Solaris Pidgin (see pidgin(1)) May Allow
   Remote Unprivileged Users to Access Arbitrary Files
     _________________________________________________________________

   Category: Security
   Release Phase: Resolved
   Bug Id: 6913836
   Product: OpenSolaris
   Date of Resolved Release: 19-Feb-2010
   A Security Vulnerability in Solaris Pidgin (see pidgin(1)) May Allow
   Remote Unprivileged Users to Access Arbitrary Files

   1. Impact

   A vulnerability in the MSN protocol handler of libpurple(3), the
   shared library that adds support for various instant messaging
   networks to the pidgin(1) Instant Messaging client (previously known
   as Gaim), may allow remote unprivileged users to retrieve arbitrary
   files (readable by the targeted user) on the target's computer via a
   custom "smiley" request.
   Additional information on this issue can be found in the following
   document:
   CVE-2010-0013 at
   [1]http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0013

   2. Contributing Factors

   This issue can occur in the following releases:
   SPARC Platform
     * OpenSolaris based upon builds snv_99 through snv_131

   x86 Platform
     * OpenSolaris based upon builds snv_99 through snv_131

   Notes:
   1. Solaris 8 and Solaris 9 do not ship Pidgin and therefore are not
   affected by this issue. Versions of Pidgin shipped with Solaris 10 and
   versions of Gaim shipped with Solaris 10 and OpenSolaris are not
   affected by this issue.
   2. This issue affects only those systems which have the Pidgin IM
   client of a version later than 2.5.0 and prior to 2.6.5 installed.
   To determine if Pidgin is installed on the system and to check the
   version of Pidgin installed, the following command may be run:
$ /usr/bin/pidgin -v || echo "Pidgin IM client not installed"

   To determine the base build of OpenSolaris, the following command can
   be used:
$ uname -v
snv_86

   3. Symptoms

   There are no predictable symptoms that would indicate this issue has
   been exploited to access arbitrary files.

   4. Workaround

   To mitigate the impact of the described issue, remove the
   .purple/custom_smiley from user's home directory if it exists. This
   directory is not created by default, but is only created when custom
   "smileys" are first defined. This can be done by running the following
   command:
$ rm -r $HOME/.purple/custom_smiley/

   5. Resolution

   This issue is addressed in the following releases:
   SPARC Platform
     * OpenSolaris based upon builds snv_132 or later

   x86 Platform
     * OpenSolaris based upon builds snv_132 or later
