Damian Poddebniak discovered that the Cyrus IMAP server didn’t restrict
memory allocation for some command arguments which may result in denial
of service. This update backports new config directives which allow to
configure limits, additional details can be found at:
https://www.cyrusimap.org/3.6/imap/download/release-notes/3.6/x/3.6.5.html
These changes are too intrusive to be backported to the version of
Cyrus in the oldstable distribution (bullseye). If the IMAP server is used
by untrusted users an update to Debian stable/bookworm is recommended.
In addition the version of cyrus-imapd in bullseye-backports will be
updated with a patch soon.
