Description

A flaw in curl’s cookie parsing logic allows a malicious HTTP server to set<br /> &#39;super cookies&#39; that bypass the Public Suffix List check. This enables an<br /> attacker-controlled origin to inject cookies that curl subsequently scopes and<br /> transmits to unrelated third-party domains.
