CVSS 7.5 HIGH
A flaw was found in the `net/mail` package of the Go programming language. An attacker could provide specially crafted inputs to the `ParseAddress`, `ParseAddressList`, or `ParseDate` functions. This could lead to excessive consumption of CPU and memory resources, resulting in a Denial of Service (DoS) for applications processing these inputs.
