    Summary: Updated thunderbird packages fix security vulnerabilities

    Details: Updated thunderbird package fixes security vulnerabilities: * Spoofing of Email signatures II: The signature verification routine in Enigmail 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 (CVE-2018-12019). * Spoofing of Email signatures I: GnuPG 2.2.8 fixed a security bug that allows remote attackers to spoof arbitrary email signatures via the embedded "--filename" parameter in OpenPGP literal data packets. This release of Enigmail prevents the exploit for all versions of GnuPG, i.e. also if GnuPG is not updated (CVE-2018-12020).
