From first advisory:
"Cyrus' Sieve implementation contains a couple of classic string based buffer overflows in script parsing code. Anyone who can execute Sieve scripts can exploit these bugs. Versions up to libSieve 2.1.2 and Cyrus IMAP 2.1.10 are affected."
From second advisory:
"Cyrus IMAP server has a a remotely exploitable pre-login buffer overflow. I checked versions 1.4 (oldest in web page) and 2.1.10 which both had it, so apparently all versions are affected."

SOLUTION
It is recommended that all Gentoo Linux users who are running net-mail/cyrus-imapd-2.1.9-r1 update their systems as follows:
emerge rsync emerge cyrus-imapd emerge clean
If you have cyrus-imap-dev-2.1.9-r1 and/or cyrus-imap-admin-2.1.9 installed you need to update those aswell:
emerge cyrus-imap-dev and/or emerge cyrus-imap-admin
