    Package        : cyrus-imapd
    CVE ID         : CVE-2024-34055

    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.

    For the stable distribution (bookworm), this problem has been fixed in
    version 3.6.1-4+deb12u2.

    We recommend that you upgrade your cyrus-imapd packages.

    For the detailed security status of cyrus-imapd please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/cyrus-imapd
