Background

Dovecot is an open source IMAP and POP3 email server.

Description

It was discovered that Dovecot incorrectly handled deeply nested MIME parts, incorrectly handled memory when using NTLM, and incorrectly handled zero-length messages.

Impact

A remote attacker could send a specially crafted mail or send specially crafted authentication requests possibly resulting in a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Dovecot users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-mail/dovecot-2.3.11.3"
OSVersionArchitecturePackageVersionFilename
Gentooanyallnet-mail/dovecot< 2.3.11.3UNKNOWN
