A flaw was found in libcurl from versions 7.29.0 through 7.71.1. An application that performs multiple requests with libcurl's multi API, and sets the `CURLOPT_CONNECT_ONLY` option, might experience libcurl using the wrong connection. The highest threat from this vulnerability is to data confidentiality.

Acknowledgments: Name: the Curl project Upstream: Marc Aldorasi Created curl tracking bugs for this issue: Affects: fedora-all [bug 1870092] Created mingw-curl tracking bugs for this issue: Affects: fedora-all [bug 1870093] The patch provided by curl upstream applies on curl-7.71.1 whereas RHEL-7 uses curl-7.29.0, which was released in 2013. 10242 commits landed upstream in between the 7.29.0 release and the commit that fixed CVE-2020-8231. Adapting the fix on a 7 years old code base is a risky task. Bug #1683292 is a good example of what happens when such a backport goes wrong. In this case it is also difficult to verify that backported fix actually works. Is there any reproducer for the security issue in question?
