Debian DLA-1667-1 : dovecot security update

High Nessus Plugin ID 122037


The remote Debian host is missing a security update.


It was discovered that there was a vulnerability in the dovecot
IMAP/POP3 server.

A flaw in the TLS username handling could lead to an attacker logging
in as anyone else in the system if both
auth_ssl_{require_client,username_from}_cert were enabled.

For Debian 8 'Jessie', this issue has been fixed in dovecot version

We recommend that you upgrade your dovecot packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.


Upgrade the affected packages.
