operations after PUT operations. This issue could cause applications using
curl to send the wrong data, perform incorrect memory operations, or crash.
(CVE-2022-32221)
Hiroki Kurosawa discovered that curl incorrectly handled parsing .netrc
files. If an attacker were able to provide a specially crafted .netrc file,
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,
resulting in a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2022-42915)
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-2022-42916)
