FreeBSD : cyrus-imapd -- multiple-minute daemon hang via input that is mishandled during hash-table interaction (3d915d96-0b1f-11ec-8d9f-080027415d17)

Cyrus IMAP 3.4.2 Release Notes states : Fixed CVE-2021-33582: Certain user inputs are used as hash table keys during processing. A poorly chosen string hashing algorithm meant that the user could control which bucket their data was stored in, allowing a malicious user to direct many inputs to a...

Core: Hash Collision Denial of Service

It was found that string comparisons in .NET Core did not use a secure hashing algorithm. This could allow an attacker to predict string hashes and cause a denial of service by intentionally creating collisions thus forcing long look up times...
