Amazon Linux 2 : httpd (ALAS-2024-2532)

high Nessus Plugin ID 194861

Language:

Synopsis

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

Description

The version of httpd installed on the remote host is prior to 2.4.59-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2532 advisory.

 Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators to split HTTP responses.

 This issue affects Apache HTTP Server: through 2.4.58. (CVE-2023-38709)

 HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack.

 Users are recommended to upgrade to version 2.4.59, which fixes this issue. (CVE-2024-24795)

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 'yum update httpd' to update your system.
