Released Pigeonhole v0.5.3 for Dovecot v2.3.3.
by Stephan Bosch 01 Oct '18

01 Oct '18

Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.3. Only two insignificant memory leak fixes were added since the release candidate (not mentioned in the changelog). Changelog v0.5.3: - Fix assertion panic occurring when managesieve service fails to open INBOX while saving a Sieve script. This was caused by a lack of cleanup after failure. - Fix specific messages causing an assert panic with actions that compose a reply (e.g. vacation). With some rather weird input from the original message, the header folding algorithm (as used for composing the References header for the reply) got confused, causing the panic. - IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing. After finishing reading the Sieve script, the command parsing sometimes didn't continue with the search arguments. This is a time- critical bug that likely only occurs when the Sieve script is sent in the next TCP frame. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.3.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.3.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
