    CVE-2021-33582

    Summary: Updated cyrus-imapd packages fix security vulnerability

    Details: 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. (CVE-2021-33582)
