Oracle Linux 6 : httpd (ELSA-2017-2972) (Optionsbleed)

Medium Nessus Plugin ID 104002

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

From Red Hat Security Advisory 2017:2972 :

An update for httpd is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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 Bock for reporting CVE-2017-9798 and KAWAHARA Masashi for reporting CVE-2017-12171.

Solution

Update the affected httpd packages.
