Cvss 3 Severity Score

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.

From the Ubuntu Security Team

It was discovered that Redis incorrectly handled large number inputs. An attacker could possibly use this issue to case a denial of service or bypass sandbox restrictions.
