Hi,

The following vulnerability was published for cyrus-imapd.

CVE-2021-33582[0]:
| Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of
| service (multiple-minute daemon hang) via input that is mishandled
| during hash-table interaction. Because there are many insertions into
| a single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8,
| and 3.0.16.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
