A regression was found in the Red Hat Enterprise Linux 6.9 version of httpd 2.2.15-60, 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.

The remote NewStart CGSL host, running version MAIN 4.05, has httpd packages installed that are affected by a vulnerability:

  - 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)

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

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)
