Mutt is a small but very powerful text-based mail client.
NeoMutt is a command line mail reader (or MUA). It’s a fork of Mutt with added features.
It was discovered that Mutt, and NeoMutt did not properly handle certain situations where an IMAP sequence set ends with a comma.
A remote attacker could entice a user to connect to a malicious IMAP server to cause a Denial of Service condition, or other unspecified impacts.
There is no known workaround at this time.
