Description
CVE-2020-14147: https://nvd.nist.gov/vuln/detail/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.
