Details

Axel Chong discovered that curl incorrectly handled percent-encoded URL
separators. A remote attacker could possibly use this issue to trick curl
into using the wrong URL and bypass certain checks or filters. This issue
only affected Ubuntu 22.04 LTS. (CVE-2022-27780)

Florian Kohnhuser discovered that curl incorrectly handled returning a
TLS server’s certificate chain details. A remote attacker could possibly
use this issue to cause curl to stop responding, resulting in a denial of
service. (CVE-2022-27781)

connection when certain options had been changed, contrary to expectations.
