Announcement ID: openSUSE-SU-2020:1822-1
Rating: moderate
References: #1157594 #1177967
Cross-References: CVE-2020-15917

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 recipient and then
* bug 4373, ‘attach mailto URI double free’
* bug 4374, ‘insert mailto URI misses checks’
* bug 4384, ‘U+00AD (soft hyphen) changed to space in Subject’
* bug 4386, ‘Allow Sieve config without userid without warning’
* Add missing SSL settings when cloning accounts.
* Parsing of command-line arguments.
* PGP Core plugin: fix segv in address completion with a keyring.
* Libravatar plugin: fixes to image display.

– Disable python-gtk plugin on suse_version > 1500: still relying
on python2, which is EOL.

– Update to 3.17.6:

* It is now possible to ‘Inherit Folder properties and processing rules
from parent folder’ when creating new folders with the move message
and copy message dialogues.
* A Phishing warning is now shown when copying a phishing URL, (in
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 ‘None’
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’
* bug 4342, ‘Import mbox file command doesn’t work twice on a row’
* fix STARTTLS protocol violation
* fix initial debug line
* fix fat-fingered crash when v (hiding msgview) is pressed just before
c (check signature)
* fix non-translation of some Templates strings
