An update that solves one vulnerability and has two fixes
is now available.

Description:

This update for shim fixes the following issues:

- Update to the unified shim binary from SUSE Linux Enterprise 15-SP1
(bsc#1168994)

This update addresses the "BootHole" security issue (master CVE
CVE-2020-10713), by disallowing binaries signed by the previous SUSE UEFI
signing key from booting.

This update should only be installed after updates of grub2, the Linux
kernel and (if used) Xen from July / August 2020 are applied.

Additional fixes:

+ shim-install: install MokManager to \EFI\boot to process the pending MOK
request (bsc#1175626, bsc#1175656)
