CVE-2020-14147

An integer overflow in the getnum function in lua_struct.c in Redis before
6.0.3 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. NOTE: this
issue exists because of a CVE-2015-8080 regression.
