IMAP.LOGIN.Command.Buffer.Overflow

description-logoDescription

This vulnerability affects the Cyrus IMAP server. The vulnerability is a stack-based LOGIN buffer overflow. The application fails to check the username length before it is copied into a temporary stack buffer, making a buffer overflow possible. A remote attacker may exploit this to cause denial of service or execute arbitrary code leading to system compromise.
