"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2025:0693 advisory.

    Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can
    contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data
    set. You can persist it either by dumping the data set to disk every once in a while, or by appending each
    command to a log.

    Security Fix(es):

    * redis: heap overflow in the lua cjson and cmsgpack libraries (CVE-2022-24834)

    * redis: possible bypass of Unix socket permissions on startup (CVE-2023-45145)

    * redis: Lua library commands may lead to stack overflow and RCE in Redis (CVE-2024-31449)

    * redis: Denial-of-service due to unbounded pattern matching in Redis (CVE-2024-31228)

    * redis: Redis' Lua library commands may lead to remote code execution (CVE-2024-46981)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
