TITLE

Apache HTTP Server of server/request.c Inside ap_some_auth_required Vulnerabilities that prevent access restrictions in functions

DESCRIPTION

The ap_some_auth_required function in server/request.c in the Apache HTTP Server 2.4.x before 2.4.14 does not consider that a Require directive may be associated with an authorization setting rather than an authentication setting, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging the presence of a module that relies on the 2.2 API behavior. Apache HTTP Server is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may lead to further attacks. The server is fast, reliable and extensible through a simple API. The vulnerability stems from the fact that when the program does not require authentication, the Require directive will still be used for authorization settings and in displayed in the configuration. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: httpd security update Advisory ID: RHSA-2015:1667-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-1667.html Issue date: 2015-08-24 CVE Names: CVE-2015-3183 CVE-2015-3185 ===================================================================== 1. Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 7) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.

In some configurations, apache2 would fail to start with a spurious error message about the certificate chain. This update fixes this problem. For reference, the text of the original advisory follows: Several vulnerabilities have been found in the Apache HTTPD server. A malicious client could force the server to misinterpret the request length, allowing cache poisoning or credential hijacking if an intermediary proxy is in use. CVE-2015-3185 A design error in the "ap_some_auth_required" function renders the API unusuable in apache2 2.4.x. The fix backports the new "ap_some_authn_required" API from 2.4.16. This issue does not affect the oldstable distribution (wheezy). In addition, the updated package for the oldstable distribution (wheezy) removes a limitation of the Diffie-Hellman (DH) parameters to 1024 bits. This limitation may potentially allow an attacker with very large computing resources, like a nation-state, to break DH key exchange by precomputation. The updated apache2 package also allows to configure custom DH parameters. More information is contained in the changelog.Debian.gz file. These improvements were already present in the stable, testing, and unstable distributions. For the oldstable distribution (wheezy), this problem has been fixed in version 2.2.22-13+deb7u6. The other distributions were not affected by the regression. We recommend that you upgrade your apache2 packages. CVE-ID CVE-2015-5911 : Zachary Jones of WhiteHat Security Threat Research Center OS X Server 5.0.3 may be obtained from the Mac App Store. This software, such as Apache HTTP Server, is common to multiple JBoss middleware products, and is packaged under Red Hat JBoss Core Services to allow for faster distribution of updates, and for a more consistent update experience. This release of Red Hat JBoss Core Services Apache HTTP Server 2.4.23 Service Pack 2 serves as an update for Red Hat JBoss Core Services Apache HTTP Server 2.4.23 Service Pack 1, and includes bug fixes, which are documented in the Release Notes document linked to in the References. Security Fix(es): * It was discovered that the httpd's mod_auth_digest module did not properly initialize memory before using it when processing certain headers related to digest authentication. (CVE-2015-3185) * A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. Upstream acknowledges Karthikeyan Bhargavan (Inria) and GaA<<tan Leurent (Inria) as the original reporters of CVE-2016-2183. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.
