Ubuntu 16.04 LTS : Dovecot regression (USN-3258-2)

high Nessus Plugin ID 99303

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3258-2 advisory.

 USN-3258-1 intended to fix a vulnerability in Dovecot. Further investigation revealed that only Dovecot versions 2.2.26 and newer were affected by the vulnerability. Additionally, the change introduced a regression when Dovecot was configured to use the dict authentication database. This update reverts the change. We apologize for the inconvenience.



Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
