New mutt packages are available for Slackware 14.0, 14.1, 14.2, and -current to
fix a security issue.

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/mutt-1.10.1-i586-2_slack14.2.txz: Rebuilt.
Mutt had incorrect error handling when initially connecting to an IMAP
server, which could result in an attempt to authenticate without enabling TLS.
For more information, see:
https://vulners.com/cve/CVE-2020-28896
(* Security fix *)

Where to find the new packages:

Thanks to the friendly folks at the OSU Open Source Lab
