Amazon Linux 2 : httpd (ALAS-2020-1427)

medium Nessus Plugin ID 136750

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 2.4.43-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1427 advisory.

 In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server. (CVE-2020-1934)

 In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL. (CVE-2020-1927)

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.
