APP: Redis Lua Scripting Component getnum Integer Overflow
This signature detects attempts to exploit a known vulnerability in the Redis Lua Scripting component. This vulnerability is due to the vulnerable server incorrectly parsing specific Lua scripts. A successful attack can lead to an Integer overflow and cause denial of service to the running application.
Extended Description
Integer overflow in the getnum function in lua_struct.c in Redis 2.8.x before 2.8.24 and 3.0.x before 3.0.6 allows context-dependent attackers with permission to run Lua code in a Redis session to cause a denial of service (memory corruption and application crash) or possibly bypass intended sandbox restrictions via a large number, which triggers a stack-based buffer overflow.
