FreeBSD : mail/dovecot -- multiple vulnerabilities (bd98066d-4ea4-11eb-b412-e86a64caca56)

medium Nessus Plugin ID 144841

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Aki Tuomi reports :

When imap hibernation is active, an attacker can cause Dovecot to discover file system directory structure and access other users' emails using specially crafted command. The attacker must have valid credentials to access the mail server.

Mail delivery / parsing crashed when the 10 000th MIME part was message/rfc822 (or if parent was multipart/digest). This happened due to earlier MIME parsing changes for CVE-2020-12100.

Solution

Update the affected package.
