Synopsis

The remote Fedora host is missing a security update.

Description

CVE-2020-12100: Parsing mails with a large number of MIME parts could have resulted in excessive CPU usage or a crash due to running out of stack memory. CVE-2020-12673: Dovecot's NTLM implementation does not correctly check message buffer size, which leads to reading past allocation which can lead to crash. CVE-2020-10967: lmtp/submission:
Issuing the RCPT command with an address that has the empty quoted string as local-part causes the lmtp service to crash. CVE-2020-12674:
Dovecot's RPA mechanism implementation accepts zero-length message, which leads to assert-crash later on.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected 1:dovecot package.
