- update pigeonhole to 0.5.0.1
- imap4flags extension: Fix binary corruption occurring when
setflag/addflag/removeflag flag-list is a variable.
- sieve-extprograms plugin: Fix segfault occurring when used in
IMAPSieve context.
- drop 321a39be974deb2e7eff7b2a509a3ee6ff2e5ae1.patch
- pull backport patch dovecot-2.3.0.1-over-quota-lmtp-crash.patch

* CVE-2017-15130: TLS SNI config lookups may lead to excessive
memory usage, causing imap-login/pop3-login VSZ limit to be
reached and the process restarted. This happens only if Dovecot
config has local_name { } or local { } configuration blocks and
attacker uses randomly generated SNI servernames.
* CVE-2017-14461: Parsing invalid email addresses may cause a
crash or leak memory contents to attacker. For example, these
memory contents might contain parts of an email from another
user if the same imap process is reused for multiple users.
First discovered by Aleksandar Nikolic of Cisco Talos.
Independently also discovered by "flxflndy" via HackerOne.
* CVE-2017-15132: Aborted SASL authentication leaks memory in
login process.
* Linux: Core dumping is no longer enabled by default via
PR_SET_DUMPABLE, because this may allow attackers to bypass
chroot/group restrictions. Found by cPanel Security Team.
Nowadays core dumps can be safely enabled by using "sysctl -w
fs.suid_dumpable=2". If the old behaviour is wanted, it can
still be enabled by setting:
import_environment=$import_environment PR_SET_DUMPABLE=1
- imap-login with SSL/TLS connections may end up in infinite loop
