CVE-2022-3559 version range fix

Hello,

The NVD database entry for CVE-2022-3559 indicates that "unknown" versions of exim is affected, with a "-" in the CPE version field:

cpe:2.3:a:exim:exim:-:*:*:*:*:*:*:*

However, the Debian Security Tracker at
https://security-tracker.debian.org/tracker/CVE-2022-3559 gives us some details on which commits fix the issue:

https://git.exim.org/exim.git/commit/4e9ed49f8f12eb331b29bd5b6dc3693c520fddc2 (exim-4.97-RC0) Important follow-up fixes:
https://git.exim.org/exim.git/commit/d8ecc7bf97934a1e2244788c610c958cacd740bd (exim-4.97-RC0)
https://git.exim.org/exim.git/commit/158dff9936e36a2d31d037d3988b9353458d6471 (exim-4.97-RC0)
https://git.exim.org/exim.git/commit/32da6327e434e986a18b75a84f2d8c687ba14619 (exim-4.97-RC0)

So while we cannot identify easily when the vulnerability was introduced, we can for sure say it was fixed in exim 4.97.

Would it be possible to update your CVE entry to indicate that the issue only exists up to (excluding) exim 4.97 ?

Thanks in advance!
