The Simple Authentication and Security Layer (SASL) is an authentication layer used in Internet protocols. The SASL is not a protocol, but rather a framework that provides developers of applications and shared libraries with mechanisms for authentication, data integritychecking, and encryption. There are a couple of known SASL vulnerabilities that we want to make you aware of. Although patches have been issued, not everyone has implemented them. These vulnerabilities were fixed by Denial of Service (Dovecot) but there has been a bad adoption rate.”]
