Description

A flaw was found in curl that verifies a given cookie domain against the Public Suffix List. This issue could allow a malicious HTTP server to set "super cookies" in curl that are passed back to more origins than what is otherwise allowed or possible.

Statement

When curl is built without PSL support, it cannot protect against this problem but it is expected to not allow "too wide" cookies when PSL support is enabled.
