FreeBSD : mutt -- denial of service (387bbade-5d1d-11eb-bf20-4437e6ad11c4)

medium Nessus Plugin ID 145274

Synopsis

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

Description

Tavis Ormandy reports :

rfc822.c in Mutt through 2.0.4 allows remote attackers to cause a denial of service (mailbox unavailability) by sending email messages with sequences of semicolon characters in RFC822 address fields (aka terminators of empty groups). A small email message from the attacker can cause large memory consumption, and the victim may then be unable to see email messages from other persons.

Solution

Update the affected package.
