<div style="direction: ltr; text-align: left;">Kia Ora Dochelp,</div>
<div style="direction: ltr; text-align: left;"><br>
</div>
<div style="direction: ltr; text-align: left;">Recently we have seen CVE-2024-21427 and CVE-2024-20674 issued.</div>
<div style="direction: ltr; text-align: left;"><br>
</div>
<div style="direction: ltr; text-align: left;">The first <span style="font-size: 14.6667px;">
CVE-2024-21427</span>, we know what the details are from our report, but we don't have details of the protocol change from the MS side, so would like the full details in case there were protocol changes we didn't anticipate. </div>
<div style="direction: ltr; text-align: left;"><br>
</div>
<div style="direction: ltr; text-align: left;">We don't have any details of the protocol changes for
<span style="font-size: 14.6667px;">CVE-2024-20674, and as it is marked Critical we would like to ensure we don't have a similar issue or can follow any protocol changes made for interoperability. </span></div>
<div style="direction: ltr; text-align: left; font-size: 14.6667px;"><br>
</div>
<div style="direction: ltr; text-align: left; font-size: 14.6667px;">Finally, we have noticed in November (or earlier) that the Server signature in the Kerberos PAC is no longer RC4_HMAC, even with RC4 tickets. This makes a lot of sense, but I don't see any
documentation and I would like to update our implementation to match.</div>
<div style="direction: ltr; text-align: left; font-size: 14.6667px;"><br>
</div>
<div style="direction: ltr; text-align: left;">We would greatly appreciate any information that is available on these recent Kerberos protocol changes. </div>
<div style="direction: ltr; text-align: left; font-size: 14.6667px;"><br>
</div>
<div style="direction: ltr; text-align: left; font-size: 14.6667px;">Thanks,</div>
<div style="direction: ltr; text-align: left; font-size: 14.6667px;"><br>
