Astra Linux – Vulnerability in dovecot

Sending the “NOOP ...” command with 4000 opening and closing parentheses results in an additional 1MB of memory usage. Longer commands will cause the client to disconnect. This 1MB of memory can be reserved for longer periods of time by not sending the command that ends with LF. Thus, an attacker...
