Thunderbird 78.6.1 has been released today (January 11).
For some reason, the release notes are not available yet:
but the security advisory is:
It fixes the same issue as Firefox 78.6.1 (Bug 28034).
The updated packages fix a security vulnerability:
Use-after-free write when handling a malicious COOKIE-ECHO SCTP chunk. (CVE-2020-16044)
Updated packages in core/updates_testing:
64-bit Plasma system, i5 2500, 16GB RAM, Intel graphics, wired Internet connection.
Used QA Repo to download all files, even though I knew that they wouldn't all be needed. Updated the US English version. No installation issues.
Checked my email, received some from QA, some from others. Sent test message from a gmail account to my yahoo account, and replied. Read newsgroup messages.
I don't use enigmail or the calendar, but what I do use works OK.
RedHat has issued an advisory for this today (January 13):
On mga7-64 kernel-desktop plasma
packages installed cleanly:
email (POP, SMTP): OK
Address book: OK
looks OK for mga7-64
