Details

USN-6237-1 fixed vulnerabilities in curl. The update caused a certificate
wildcard handling regression on Ubuntu 22.04 LTS. This update fixes the
problem.

We apologize for the inconvenience.

Original advisory 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)
