Summary

curl regression

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)
