Redis is an open source, in-memory database that persists on disk.
An authenticated user may use a specially crafted Lua script to
trigger a stack buffer overflow in the bit library, which may
potentially lead to remote code execution. The problem exists in
all versions of Redis with Lua scripting. This problem has been
fixed in Redis versions 6.2.16, 7.2.6, and 7.4.1. Users are advised
to upgrade. There are no known workarounds for this vulnerability.
