Description

Redis 6 contains multiple security vulnerabilities related to its Lua scripting engine, including integer overflow leading to potential remote code execution (CVE-2025-46817). Authenticated users could execute Lua scripts as different users (CVE-2025-46818), and specially crafted Lua scripts can cause denial of service (CVE-2025-46819). Additionally, a Lua use-after-free vulnerability may lead to remote code execution (CVE-2025-49844). These issues have been addressed in Redis version 6.2.20-1.module_el8.10.0+4056+739731b0.
