Security update for claws-mail (moderate)

An update that solves one vulnerability and has one errata
is now available.

Description:

This update for claws-mail fixes the following issues:

• Additional cleanup of the template handling

claws-mail was updated to 3.17.8 (boo#1177967)

 * Shielded template's |program{} and |attach_program{} so that the
   command-line that is executed does not allow sequencing such as with
   && || ;, preventing possible execution of nasty, or at least
   unexpected, commands
 * bug fixes: claws#4376
 * updated English, French, and Spanish manuals

• Update to 3.17.7

  • Image Viewer: Image attachments, when displayed, are now resized to
    fit the available width rather than the available height.
  • -d is now an alias to --debug.
  • Libravatar plugin: New styles supported: Robohash and Pagan.
  • SpamAssassin plugin: The ‘Maximum size’ option now matches
    SpamAssassin’s maximum; it can now handle messages up to 256MB.
