Redis is an open source, in-memory database that persists on disk. When
using the Redis Lua Debugger, users can send malformed requests that cause
the debugger’s protocol parser to read data beyond the actual buffer. This
issue affects all versions of Redis with Lua debugging support (3.2 or
newer). The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14.
