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.
Debian Linux Security Advisory 5587-1 - Two security issues were discovered in Curl: Cookies were incorrectly validated against the public suffix list of domains and in same cases HSTS data could fail to save to disk.
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.
