Redis is an in-memory database that persists on disk. A specially crafted
Lua script executing in Redis can trigger a heap overflow in the cjson
library, and result with heap corruption and potentially remote code
execution. The problem exists in all versions of Redis with Lua scripting
support, starting from 2.6, and affects only authenticated and authorized
users. The problem is fixed in versions 7.0.12, 6.2.13, and 6.0.20.
