"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 BAPck for reporting CVE-2017-9798
and KAWAHARA Masashi for reporting CVE-2017-12171.

Note that Tenable Network Security has attempted to extract the
preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.");
