CVE-2023-46218 Open this link in a new tabHow to fix?
Upgrade Amazon-Linux:2 libcurl to version 0:8.3.0-1.amzn2.0.5 or higher.
This issue was patched in ALAS2-2024-2385.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcurl package and not the libcurl package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2 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.
