This issue was patched in RHSA-2024:1316.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jbcs-httpd24-httpd-manual package and not the jbcs-httpd24-httpd-manual package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

This flaw allows a malicious HTTP server to set "super cookies" in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains.

It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with domain=co.UK when the URL used a lower case hostname curl.co.uk, even though co.uk is listed as a PSL domain.
