Dovecot source code audit

[Timo Sirainen]

Mozilla sponsored source code audit for Dovecot. So thanks to them we have our first public code audit: https://wiki.mozilla.org/MOSS/Secure_Open_Source/Completed#dovecot

Dates: October 2016 - January 2017

dovecot is a POP and IMAP mailserver; it is used in 68% of IMAP server deployments worldwide. The audit was performed by Cure53.

The team found the following problems:

	• 3 Low

The Cure53 team were extremely impressed with the quality of the dovecot code. They wrote: "Despite much effort and thoroughly all-encompassing approach, the Cure53 testers only managed to assert the excellent security-standing of Dovecot. More specifically, only three minor security issues have been found in the codebase, thus translating to an exceptionally good outcome for Dovecot, and a true testament to the fact that keeping security promises is at the core of the Dovecot development and operations."
