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


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.
* LiteHTML viewer plugin: The UI is now translatable. Bug fixes:
* bug 4313, 'Recursion stack overflow with rebuilding folder tree'
* bug 4372, '[pl_PL] Crash after "Send later" without

from parent folder' when creating new folders with the move message
and copy message dialogues.

addition to clicking a phishing URL).
* The progress window when importing an mbox file is now more responsive.
* A warning dialogue is shown if the selected privacy system is
and automatic signing amd/or encrypting is enabled.
* Python plugin: pkgconfig is now used to check for python2. This
enables the Python plugin (which uses python2) to be built on newer
systems which have both python2 and python3. Bug fixes:
* bug 3922, 'minimize to tray on startup not working'
* bug 4220, 'generates files in cache without content'
* bug 4325, 'Following redirects when retrieving image'
