medium Nessus Plugin ID 83549

Synopsis

The remote Fedora host is missing a security update.

Description

fixes CVE-2015-3420: SSL/TLS handshake failures leading to a crash of the login process

- dovecot updated to 2.2.16

- auth: Don't crash if master user login is attempted without any configured master=yes passdbs

- Parsing UTF-8 text for mails could have caused broken results sometimes if buffering was split in the middle of a UTF-8 character. This affected at least searching messages.

- String sanitization for some logged output wasn't done properly: UTF-8 text could have been truncated wrongly or the truncation may not have happened at all.

- fts-lucene: Lookups from virtual mailbox consisting of over 32 physical mailboxes could have caused crashes.
