Details
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.
(CVE-2023-46218)
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.
