Description:


   Various remote triggerable crashes in pidgin have been
   fixed:

   * CVE-2012-1178: In some situations the MSN server
   sends text that isn't UTF-8 encoded, and Pidgin fails to
   verify the text's encoding. In some cases this can lead to
   a crash when attempting to display the text ().
   * CVE-2012-1178/CVE-2012-2318: Incoming messages with
   certain characters or character encodings can cause clients
   to crash.
   * CVE-2012-2214: A series of specially crafted file
   transfer requests can cause clients to reference invalid
   memory. The user must have accepted one of the file
   transfer requests.
