Amazon Linux 2023 : valkey, valkey-devel (ALAS2023-2026-3265)

medium Nessus Plugin ID 371839

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3265 advisory.

hiredis commit 29ea279 (post-v1.5.0) contains an uncontrolled memory allocation vulnerability in its RESP aggregate parser. (CVE-2026-88382)

A flaw was found in Redis community. The cluster bus packet parser, responsible for handling PING, PONG, and MEET packets, fails to properly validate string-carrying extensions for null-termination. This oversight allows a remote attacker to craft a malicious packet, leading to an out-of-bounds read when the packet's payload is processed. Successful exploitation of this vulnerability could result in the disclosure of sensitive information or a remote denial of service (DoS). (CVE-2026-92925)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update valkey --releasever 2023.12.20261026' or or 'dnf update --advisory ALAS2023-2026-3265 --releasever 2023.12.20261026' to update your system.
