12156786-b18a-11eb-8cba-080027b00c2ecyrus-imapd -- Remote authenticated users could bypass intended access restrictions on certain server annotations.

Cyrus IMAP 3.4.1 Release Notes states:

Fixed CVE-2021-32056: Remote authenticated users could bypass intended access restrictions on certain server annotations. Additionally, a long-standing bug in replication did not allow server annotations to be replicated. Combining these two bugs, a remote authenticated user could stall replication, requiring administrator intervention.

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 single bucket. Each subsequent insertion to the same bucket requires a strcmp of every other entry in it. At tens of thousands of entries, each new insertion could keep the CPU busy in a strcmp loop for minutes. The string hashing algorithm has been replaced with a better one, and now also uses a random seed per hash table, so malicious inputs cannot be precomputed.
