Version              : 1.36~1+deb10u2 (note: binary packages are versioned as
Importance           : medium

Shim is a minimalist boot loader which allows signatures of other UEFI
binaries to be verified against either the Secure Boot DB/DBX or against
a built-in signature database. 

The version of Shim included in the recent "buster" point release features a
regression which can lead to systems running the "arm64" architecture failing
to boot. This update resolves that issue by reverting to an older version of
the software on that architecture.

If you use shim on arm64, we recommend that you install this update.
