[Bug 1633220] Re: Dovecot panics when sieve filter outputs much data

 

This bug was fixed in the package dovecot - 1:2.2.25-1ubuntu1

---------------
dovecot (1:2.2.25-1ubuntu1) zesty; urgency=medium

  * Merge with Debian (LP: #1633220); Remaining Changes:
    + Add updated autopkgtest to debian/tests/*.
    + Drop build dependency on libstemmer-dev (universe)
    + Use Snakeoil SSL certificates by default
      - d/control: Depend on ssl-cert
    + Add mail-stack-delivery
      - add package in d/rules, d/control
      - add d/*mail-stack-delivery* maintainer scripts and default conf
      - d/mail-stack-delivery.preinst: Move previously installed backups and
        config files to a new package namespace.
      - d/mail-stack-delivery.README.Debian clarified use of configuration files
    + Disable dovecot-lucene plugin as it had various issues, has universe
      dependencies and is deprecated in favor of solr anyway.
    + handle conffile removal of /etc/init/dovecot.conf (due to dropping
      upstart). Can be removed once no upgrade path from <yakkety is left.
  * Added changes:
    + Fix FTBFS of dovecot 2.2.25 in Ubuntu due to being incompatible with
      -Bsymbolic-functions linker flag (LP: #1636781).
  * Dropped Changes as they got accepted in Debian:
    + add lsb base dependency to ensure debian/dovecot-core.dovecot.init is
      working correctly
    + Add ufw integration:
      - d/dovecot-core.ufw.profile: new ufw profile.
      - d/rules: install profile in dovecot-core.
      - d/control: dovecot-core - suggest ufw.
    + Add apport hook:
      - d/rules, d/source_dovecot.py
    + Remove lintian override for drac

Title:
  Dovecot panics when sieve filter outputs much data

Status in dovecot package in Ubuntu:
  Fix Released
Status in dovecot source package in Xenial:
  Triaged
Status in dovecot source package in Yakkety:

Bug description:
  When using dovecot with vnd.dovecot.filter, where the filter returns
  at least ~60KB of data back to dovecot, dovecot panics (see dovecot
  log in attached apport report).

  The error's origin is the pigeonhole plugin. The described error is
  already fixed in the github repo for sieve-pigeonhole [1].

  We successfully managed to apply the patch locally for ubuntu's
  current version of pigeonhole (0.4.13 (7b14904)) by simply cherry
  picking the mentioned commit.

  System information:
    Description:	Ubuntu 16.04.1 LTS
    Release:	16.04
    dovecot-core:
      Installed: 1:2.2.22-1ubuntu2.1
    dovecot-sieve:
      Installed: 1:2.2.22-1ubuntu2.1

    $ doveconf | head -n2
    # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf
    # Pigeonhole version 0.4.13 (7b14904)
