usn-6237-1
Vulnerability from osv_ubuntu
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)
