This update for Mozilla Thunderbird to version 52.7 fixes multiple issues.

The following bugs were fixed:

- Searching message bodies of messages in local folders, including filter
and quick filter operations, did not find content in message attachments
- Better error handling for Yahoo accounts

The following security fixes are included as part of the mozilla platform.
In general, these flaws cannot be exploited through email in Thunderbird
because scripting is disabled when reading mail, but are potentially risks
in browser or browser-like contexts (MFSA 2018-09, bsc#1085130, bsc#1085671):
