Ubuntu Security Notice 6641-1 - Harry Sintonen discovered that curl incorrectly handled mixed case cookie domains. A remote attacker could possibly use this issue to set cookies that get sent to different and unrelated sites and domains.

When saving HSTS data to an excessively long file name, curl could end up removing all contents, making subsequent requests using that file unaware of the HSTS status they should otherwise use.

Ubuntu Security Notice 6535-1 - Harry Sintonen discovered that curl incorrectly handled mixed case cookie domains. A remote attacker could possibly use this issue to set cookies that get sent to different and unrelated sites and domains. Maksymilian Arciemowicz discovered that curl incorrectly handled long file names when saving HSTS data. This could result in curl losing HSTS data, and subsequent requests to a site would be done without it, contrary to expectations. This issue only affected Ubuntu 23.04 and Ubuntu 23.10.

This flaw allows a malicious HTTP server to set "super cookies" in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain.
