Apache James server JMAP HTML to text plain implementation in versions below 3.8.2 and 3.7.6 is subject to unbounded memory consumption that can result in a denial of service.
Users are recommended to upgrade to version 3.7.6 and 3.8.2, which fix this issue.
Similarly to CVE-2024-34055, Apache James is vulnerable to denial of service through the abuse of IMAP literals from both authenticated and unauthenticated users, which could be used to cause unbounded memory allocation and very long computations
Version 3.7.6 and 3.8.2 restrict such illegitimate use of IMAP literals.
