It was discovered, that redis, a persistent key-value database, due to a packaging issue, is prone to a (Debian-specific) Lua sandbox escape
Affects Debian packages of redis that provide the Lua library as a dynamic library. Fixed in Debian package version 5:5.0.14-1+deb10u2.

Questions about CVE-2022-0543
What does this mean?
A packaging issue in Debian's redis build allows the Lua sandbox to be escaped. An attacker who can run arbitrary Lua code could potentially execute arbitrary shell commands, which the advisory describes as potentially leading to remote code execution.Source: bugs.debian.org, lists.debian.org
Am I affected, and how do I check?
The issue is limited to Debian packages of redis where the Lua library is provided as a dynamic library, and it requires the ability to execute arbitrary Lua code. Compare the installed Debian redis package version with 5:5.0.14-1+deb10u2 to see whether it predates the fix.Source: bugs.debian.org, lists.debian.org
What should I do about it?
Upgrade the Debian redis package to 5:5.0.14-1+deb10u2 or a later version.Source: bugs.debian.org, lists.debian.org
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-03-28, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
