+update edk2 submodule & binaries to edk2-stable202008
+
+edk2-stable201911 will be tagged soon:
+
+  https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Release-Planning
+
+  https://github.com/tianocore/edk2/releases/tag/edk2-stable201911
+  [upcoming link]
+
+It should be picked up by QEMU, after the v4.2.0 release.
+
+Relevant fixes / features in edk2, since edk2-stable201905 (which is
+what QEMU bundles at the moment, from LP#1831477):
+
+- enable UEFI HTTPS Boot in ArmVirtQemu* platforms
+  https://bugzilla.tianocore.org/show_bug.cgi?id=1009
+  (this is from edk2-stable201908)
+
+- fix CVE-2019-14553 (Invalid server certificate accepted in HTTPS Boot)
+  https://bugzilla.tianocore.org/show_bug.cgi?id=960
+
+- consume OpenSSL-1.1.1d, for fixing CVE-2019-1543, CVE-2019-1552 and
+  CVE-2019-1563
+  https://bugzilla.tianocore.org/show_bug.cgi?id=2226
+
+Hi Laszlo,
+
+Do you have a particular reason to update the submodule *after* the v4.2.0 release?
+I'd rather see QEMU 4.2 released with edk2-stable201911, as it fixes various CVE (therefore a patch for 4.2-rc4 seems acceptable to me).
+
+
+Yes, I do have a reason for delaying this LP until after 4.2.0 is out.
+
+When I filed this ticket (on 2019-Nov-12), QEMU had already entered the 4.2.0 soft feature freeze (on 2019-Oct-29). Despite possible appearances, this LP is actually a feature addition -- that's why I also set "Tags: feature-request" when I filed this LP.
+
+The reason this is not a fix but a feature addition is the following:
+- CVE-2019-14553 is irrelevant (doesn't exist) until we enable HTTPS Boot,
+- we have not enabled HTTPS Boot earlier exactly because of CVE-2019-14553,
+- the plan is to enable HTTPS Boot now, with CVE-2019-14553 fixed,
+- so what remains are CVE-2019-1543, CVE-2019-1552 and CVE-2019-1563, which are native OpenSSL problems.
+
+The upstream edk2 project advanced to OpenSSL 1.1.1d because of the last point (i.e. because of those three OpenSSL CVEs). That submodule update was tracked in:
+
+https://bugzilla.tianocore.org/show_bug.cgi?id=2226
+
+As you can see:
+
+(1) there was zero analysis or explanation how those OpenSSL CVEs would *actually* affect edk2 platforms,
+
+(2) edk2 advanced to OpenSSL 1.1.1d (on 2019-Nov-05) approximately two months after upstream OpenSSL 1.1.1d was released (on 2019-Sep-10).
+
+Furthermore,
+
+(3) all the listed CVEs are marked "low severity":
+
+https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-1543
+https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-1552
+https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-1563
+
+(The first two items are declared low severity on cve.mitre.org, while the last item is declared low severity in <https://www.openssl.org/news/secadv/20190910.txt>.)
+
+These points (1) through (3) tell me that the edk2 advance was more or less "better safe than sorry" or "cargo cult".
+
+While that approach is not necessarily wrong, if you have infinite amounts of time, my capacity falls near the other end of the spectrum. If someone runs QEMU in production, they should build their firmware from source anyway -- the bundling of edk2 binaries with QEMU is a convenience.
+
+If you'd like to submit a QEMU patch set (just for the sake of the CVE fixes, not the HTTPS Boot feature), and are willing to make the case for getting that into 4.2-rc4, I won't block it, but I don't think it's worth the churn, to be honest.
+
+Thanks!
+Laszlo
