FreeBSD : mail/dovecot -- multiple vulnerabilities (87a07de1-e55e-4d51-bb64-8d117829a26a)

high Nessus Plugin ID 139589

Language:

Synopsis

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

Description

Aki Tuomi reports :

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..

Dovecot's NTLM implementation does not correctly check message buffer size, which leads to reading past allocation which can lead to crash

lmtp/submission: Issuing the RCPT command with an address that has the empty quoted string as local-part causes the lmtp service to crash.

Dovecot's RPA mechanism implementation accepts zero-length message, which leads to assert-crash later on.

Solution

Update the affected package.
