From: Deepak Rathore <deeratho@cisco.com>

Refine the CVE_STATUS description for CVE-2022-0543 to provide
a more precise explanation of this Debian-specific vulnerability.

The vulnerability originates from Debian's packaging methodology,
which loads system-wide Lua libraries (lua-cjson, lua-cmsgpack),
enabling Lua sandbox escape. Upstream Redis builds, including
those built by Yocto/OpenEmbedded, utilize embedded Lua from the
deps/ directory and are therefore not affected by this issue.

It is also fixed in Debian with this commit:
https://salsa.debian.org/lamby/pkg-redis/-/commit/c7fd665150dc4769402cae97d1152b3c6e4366f0
