Ubuntu - low

Summary

[none]

Details

A flaw in curl's cookie parsing logic allows a malicious HTTP server to set "super cookies" that bypass the Public Suffix List check. This enables an attacker-controlled origin to inject cookies that curl will subsequently scope and transmit to unrelated third-party domains.
