Summary
curl regression
Details

USN-5079-2 fixed vulnerabilities in curl. One of the fixes introduced a regression. This update fixes the problem.

Original advisory details:

Patrick Monnerat discovered that curl incorrectly handled upgrades to TLS. When receiving certain responses from servers, curl would continue without TLS even when the option to require a successful upgrade to TLS was specified. (CVE-2021-22946)

Patrick Monnerat discovered that curl incorrectly handled responses received before STARTTLS. A remote attacker could possibly use this issue to inject responses and intercept communications. (CVE-2021-22947)
