RHEL 6 / 7 : httpd24-httpd (RHSA-2015:1666)

Synopsis

The remote Red Hat host is missing one or more security updates for httpd24-httpd.

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1666 advisory.

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)

Note: This update introduces new a new API function, ap_some_authn_required(), which correctly indicates if a request is authenticated. External httpd modules using the old API function should be modified to use the new one to completely resolve this issue.

A denial of service flaw was found in the way the mod_lua httpd module processed certain WebSocket Ping requests. A remote attacker could send a specially crafted WebSocket Ping packet that would cause the httpd child process to crash. (CVE-2015-0228)

A NULL pointer dereference flaw was found in the way httpd generated certain error responses. A remote attacker could possibly use this flaw to crash the httpd child process using a request that triggers a certain HTTP error. (CVE-2015-0253)

All httpd24-httpd users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd24-httpd service will be restarted automatically.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL httpd24-httpd package based on the guidance in RHSA-2015:1666.
