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)
