How to fix?

There is no fixed version for Debian:14 curl.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

A deeply nested multipart MIME structure constructed via the public API causes a stack overflow in libcurl during normal cleanup operations. An excessive recursion depth within curl_mime_free leads to unbounded stack frame allocation during structure traversal, ultimately crashing the host process.
