CWE-20
Exploitation vector: Network
Exploit availability: No
Vulnerable software:
Redis

Vendor: Salvatore Sanfilippo
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.
Mitigation
Update to version 6.0.3.
Vulnerable software versions
Redis: 6.0.0 - 6.0.2
