Synopsis ========
Multiple vulnerabilities have been found in Dovecot, the worst of which could allow remote attackers to cause a Denial of Service condition.
Background ==========
Dovecot is an open source IMAP and POP3 email server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/dovecot < 2.3.11.3 >= 2.3.11.3
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"
