Amazon Linux 2 : redis (ALASREDIS6-2023-002)

high Nessus Plugin ID 181950

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of redis installed on the remote host is prior to 6.2.13-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2REDIS6-2023-002 advisory.

- Redis is an in-memory database that persists on disk. A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson library, and result with heap corruption and potentially remote code execution. The problem exists in all versions of Redis with Lua scripting support, starting from 2.6, and affects only authenticated and authorized users. The problem is fixed in versions 7.0.12, 6.2.13, and 6.0.20. (CVE-2022-24834)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update redis' to update your system.
