The Git project does not distribute any binaries. You likely want to direct this to the Git for Windows project¹.

That said, it's not even clear to me that the CVE you reference affects git's usage of OpenSSL.

From a little skimming, the issue affects use of CMS (which is something like the successor to S/MIME, as far as I can tell).

The only place where git gets close to that area is if you configure it to use x509 as gpg.program. And then git uses gpgsm, which is not affected by the CVE in OpenSSL.
