CVE-2024-31449: 
Redis vulnerability analysis and mitigation

Redis, a popular open-source data structure store, disclosed a critical vulnerability (CVE-2024-31449) that affects all versions with Lua scripting functionality. The vulnerability was discovered by ankki-zsyang from Shenzhen Ankki Technologies Co.Ltd and was patched in Redis versions 6.2.16, 7.2.6, and 7.4.1 (GitHub Advisory).

The vulnerability stems from a stack buffer overflow condition in Redis's Lua bit library. The issue specifically involves the bit.tohex function where INT_MIN value handling could lead to a buffer overflow. The vulnerability has been assigned a CVSS v3.1 base score of 7.0 (High) with the vector string CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating local access requirements but high potential impact (GitHub Advisory).

If successfully exploited, this vulnerability could allow an authenticated attacker to execute arbitrary code on affected systems through a specially crafted Lua script. The vulnerability affects the confidentiality, integrity, and availability of the system, with all three aspects rated as 'High' in the CVSS scoring (GitHub Advisory).

Users are strongly advised to upgrade to the patched versions: Redis 6.2.16, 7.2.6, or 7.4.1. There are no known workarounds for this vulnerability, making the upgrade the only effective mitigation strategy (SecurityOnline).

The security community has responded promptly to this vulnerability, with Redis urging users to update their installations immediately. The vulnerability has been classified as 'High' severity, prompting immediate attention from system administrators and security professionals (SecurityOnline).
