Description
The vulnerability allows context-dependent attackers with permission to run Lua code in a Redis session to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can 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.
Remediation
Update to version 6.0.3.
