this issue could cause curl to crash, resulting in a denial of service.
This issue only affected Ubuntu 22.10. (CVE-2022-35260)

It was discovered that curl incorrectly handled certain HTTP proxy return
codes. A remote attacker could use this issue to cause curl to crash,

Hiroki Kurosawa discovered that curl incorrectly handled HSTS support
when certain hostnames included IDN characters. A remote attacker could
