[PATCH RESEND 0/1] security fix: possible heap corruption with LzmaUefiDecompressGetInfo

["Laszlo Ersek" <lersek@redhat.com>]

Repo:   https://pagure.io/lersek/edk2.git
Branch: tianocore_1816_resend
Ref:    https://bugzilla.tianocore.org/show_bug.cgi?id=1816

"RESEND" because I'm publicly posting the patch from
<https://bugzilla.tianocore.org/show_bug.cgi?id=1816#c9>.

The Reviewed-by tags on the patch originate from
<https://bugzilla.tianocore.org/show_bug.cgi?id=1816#c12> and
<https://bugzilla.tianocore.org/show_bug.cgi?id=1816#c17>.

Repeated the simple regression test at
<https://bugzilla.tianocore.org/show_bug.cgi?id=1816#c10>.

This series targets edk2-stable202011. I plan to merge it later this
week, based on Liming's R-b.

Liming, highlighting TianoCore#1816 in the "proposed features" list
could be useful.
