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

Description:

   This update for enigmail to 2.0.7 fixes the following issues:

   These security issues were fixed:

   - CVE-2018-12020: Mitigation against GnuPG signature spoofing: Email
     signatures could be spoofed via an embedded "--filename" parameter in
     OpenPGP literal data packets. This update prevents this issue from being
     exploited if GnuPG was not updated (boo#1096745)
   - CVE-2018-12019: The signature verification routine interpreted User IDs
     as status/control messages and did not correctly keep track of the
     status of multiple signatures. This allowed remote attackers to spoof
     arbitrary email signatures via public keys containing crafted primary
     user ids (boo#1097525)
   - Disallow plaintext (literal packets) outside of encrpyted packets
   - Replies to a partially encrypted message may have revealed protected
     information - no longer display PGP/MIME message part followed by
     unencrypted data (bsc#1094781)
   - Fix signature Spoofing via Inline-PGP in HTML Mails

   These non-security issues were fixed:

   - Fix filter actions forgetting selected mail folder names
   - Fix compatibility issue with Thunderbird 60b7
