Hiroki Kurosawa discovered that curl incorrectly handled HSTS support
when certain hostnames included IDN characters. A remote attacker could
possibly use this issue to cause curl to use unencrypted connections. This
issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2022-43551)
It was discovered that curl incorrectly handled denials when using HTTP
proxies. A remote attacker could use this issue to cause curl to crash,
resulting in a denial of service, or possibly execute arbitrary code.
