Debian DLA-1667-1 : dovecot security update

Medium Nessus Plugin ID 122037

Synopsis

The remote Debian host is missing a security update.

Description

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 1:2.2.13-12~deb8u5.

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.

Solution

Upgrade the affected packages.
