Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. Calling `curl_easy_pause()` within the event-based `CURLMOPT_SOCKETFUNCTION` callback triggers a use-after-free vulnerability, where libcurl attempts to store a flag using a dangling struct pointer immediately after that pointer's memory has been freed.
The bundled `curl` sources (via the Rust `curl-sys` crate) are wholly removed during the `%prep` phase to be sure we don't use them. Instead, we use the system `curl` library, so any CVE fixes only need to be made in that component on its own.
