RHEL 6 : httpd (RHSA-2017:2972)

high Nessus Plugin ID 104006

Synopsis

The remote Red Hat host is missing one or more security updates for httpd.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2972 advisory.

The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server.

Security Fix(es):

* A use-after-free flaw was found in the way httpd handled invalid and previously unregistered HTTP methods specified in the Limit directive used in an .htaccess file. A remote attacker could possibly use this flaw to disclose portions of the server memory, or cause httpd child process to crash.
(CVE-2017-9798)

* A regression was found in the Red Hat Enterprise Linux 6.9 version of httpd, causing comments in the Allow and Deny configuration lines to be parsed incorrectly. A web administrator could unintentionally allow any client to access a restricted HTTP resource. (CVE-2017-12171)

Red Hat would like to thank Hanno Bck for reporting CVE-2017-9798 and KAWAHARA Masashi for reporting CVE-2017-12171.

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

Update the RHEL httpd package based on the guidance in RHSA-2017:2972.
