An Integer Overflow issue was discovered in the struct library in the Lua subsystem in Redis before 3.2.12, 4.x before 4.0.10, and 5.x before 5.0 RC2, leading to a failure of bounds checking.
The Redis command line tool 'redis-cli' is vulnerable to a buffer overflow through the -h (host) command line parameter. The redis-cli may be used by other services; if these services do not adequately filter the host input it could lead to code execution with the privilege level of that service.
