RHEL 7 : httpd (RHSA-2015:1667)
Medium Nessus Plugin ID 85617
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated 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.
SolutionUpdate the affected packages.
