Details

Hiroki Kurosawa discovered that curl incorrectly handled validating certain
certificate wildcards. A remote attacker could possibly use this issue to
spoof certain website certificates using IDN hosts. (CVE-2023-28321)

Hiroki Kurosawa discovered that curl incorrectly handled callbacks when
certain options are set by applications. This could cause applications
using curl to misbehave, resulting in information disclosure, or a denial
of service. (CVE-2023-28322)

It was discovered that curl incorrectly handled saving cookies to files. A
local attacker could possibly use this issue to create or overwrite files.
This issue only affected Ubuntu 22.10, and Ubuntu 23.04. (CVE-2023-32001)
