USN-6237-1: curl vulnerabilities<\/p>\n

Hiroki Kurosawa discovered that curl incorrectly handled validating certain
\ncertificate wildcards. A remote attacker could possibly use this issue to
\nspoof certain website certificates using IDN hosts. (CVE-2023-28321)<\/p>\n

Hiroki Kurosawa discovered that curl incorrectly handled callbacks when
\ncertain options are set by applications. This could cause applications
\nusing curl to misbehave, resulting in information disclosure, or a denial
\nof service. (CVE-2023-28322)<\/p>\n

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