Summary
Moderate: dovecot security update
Details

Dovecot is an IMAP server for Linux and other UNIX-like systems, written primarily with security in mind. It also contains a small POP3 server, and supports e-mail in either the maildir or mbox format. The SQL drivers and authentication plug-ins are provided as subpackages.

Security Fix(es):

  • dovecot: command followed by sufficient number of newlines leads to use-after-free (CVE-2020-10958)

  • dovecot: sending mail with empty quoted localpart leads to DoS (CVE-2020-10967)
