RHEL 7 : httpd (RHSA-2015:1667)

Synopsis :

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

Description :

Updated httpd packages that fix two security issues are now available
for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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

Multiple flaws were found in the way httpd parsed HTTP requests and
responses using chunked transfer encoding. A remote attacker could use
these flaws to create a specially crafted request, which httpd would
decode differently from an HTTP proxy software in front of it,
possibly leading to HTTP request smuggling attacks. (CVE-2015-3183)

It was discovered that in httpd 2.4, the internal API function
ap_some_auth_required() could incorrectly indicate that a request was
authenticated even when no authentication was used. An httpd module
using this API function could consequently allow access that should
have been denied. (CVE-2015-3185)

All httpd users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. After
installing the updated packages, the httpd service will be restarted
automatically.
