TITLE

Cosminexus HTTP Server  and  Hitachi Web Server  Vulnerability in

DESCRIPTION

Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution. Cosminexus HTTP Server and Hitachi Web Server has a vulnerability (CVE-2016-8743) exists.May have unspecified impact. Successfully exploiting this issue may allow attackers to perform unauthorized actions. This may lead to other attacks. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201701-36 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: Apache: Multiple vulnerabilities Date: January 15, 2017 Bugs: #529130, #589226, #601736, #603130 ID: 201701-36 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in Apache, the worst of which could lead to a Denial of Service condition.

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 1 serves as a replacement for Red Hat JBoss Core Services Apache HTTP Server 2.4.23, and includes bug fixes, which are documented in the Release Notes document linked to in the References. Security Fix(es): * A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. (CVE-2016-2161) * A timing attack flaw was found in OpenSSL that could allow a malicious user with local access to recover ECDSA P-256 private keys. (CVE-2016-7056) * A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. (CVE-2016-8743) * A vulnerability was found in httpd's handling of the LimitRequestFields directive in mod_http2, affecting servers with HTTP/2 enabled. An attacker could send crafted requests with headers larger than the server's available memory, causing httpd to crash. (CVE-2016-8740) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-6304 and Shi Lei (Gear Team of Qihoo 360 Inc.) for reporting CVE-2016-8610.

Software Description: - apache2: Apache HTTP server Details: Emmanuel Dreyfus discovered that third-party modules using the ap_get_basic_auth_pw() function outside of the authentication phase may lead to authentication requirements being bypassed. This update adds a new ap_get_basic_auth_components() function for use by third-party modules. (CVE-2017-3167) Vasileios Panopoulos discovered that the Apache mod_ssl module may crash when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. (CVE-2017-7668) ChenQin and Hanno BAPck discovered that the Apache mod_mime module incorrectly handled certain Content-Type response headers. A new configuration option "HttpProtocolOptions Unsafe" can be used to revert to the previous unsafe behaviour in problematic environments. (CVE-2016-8743) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 ESM: A apache2.2-binA A A A A A A A A A A A A A A A A A A 2.2.22-1ubuntu1.12 In general, a standard system update will make all the necessary changes. X-Scanned-By: MIMEDefang 2.79 on 10.5.11.16 X-Greylist: Sender IP whitelisted, not delayed by milter-greylist-4.5.16 (mx1.redhat.com [10.5.110.26]); Wed, 12 Apr 2017 19:41:10 +0000 (UTC) -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: httpd security and bug fix update Advisory ID: RHSA-2017:0906-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:0906 Issue date: 2017-04-12 CVE Names: CVE-2016-0736 CVE-2016-2161 CVE-2016-8743 ===================================================================== 1. Summary: An update for httpd is now available for Red Hat Enterprise Linux 7. 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. 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) - aarch64, noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, 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. Security Fix(es): * It was discovered that the mod_session_crypto module of httpd did not use any mechanisms to verify integrity of the encrypted session data stored in the user's browser. A remote attacker could use this flaw to decrypt and modify session data using a padding oracle attack. (CVE-2016-0736) * It was discovered that the mod_auth_digest module of httpd did not properly check for memory allocation failures. A remote attacker could use this flaw to cause httpd child processes to repeatedly crash if the server used HTTP digest authentication. (CVE-2016-2161) * It was discovered that the HTTP parser in httpd incorrectly allowed certain characters not permitted by the HTTP protocol specification to appear unencoded in HTTP request headers. If httpd was used in conjunction with a proxy or backend server that interpreted those characters differently, a remote attacker could possibly use this flaw to inject data into HTTP responses, resulting in proxy cache poisoning. (CVE-2016-8743) Note: The fix for the CVE-2016-8743 issue causes httpd to return "400 Bad Request" error to HTTP clients which do not strictly follow HTTP protocol specification. A newly introduced configuration directive "HttpProtocolOptions Unsafe" can be used to re-enable the old less strict parsing. However, such setting also re-introduces the CVE-2016-8743 issue. Bug Fix(es): * When waking up child processes during a graceful restart, the httpd parent process could attempt to open more connections than necessary if a large number of child processes had been active prior to the restart. Consequently, a graceful restart could take a long time to complete. With this update, httpd has been fixed to limit the number of connections opened during a graceful restart to the number of active children, and the described problem no longer occurs. (BZ#1420002) * Previously, httpd running in a container returned the 500 HTTP status code (Internal Server Error) when a connection to a WebSocket server was closed. As a consequence, the httpd server failed to deliver the correct HTTP status and data to a client. With this update, httpd correctly handles all proxied requests to the WebSocket server, and the described problem no longer occurs. (BZ#1429947) * In a configuration using LDAP authentication with the mod_authnz_ldap module, the name set using the AuthLDAPBindDN directive was not correctly used to bind to the LDAP server for all queries. Consequently, authorization attempts failed. The LDAP modules have been fixed to ensure the configured name is correctly bound for LDAP queries, and authorization using LDAP no longer fails. (BZ#1420047) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing the updated packages, the httpd daemon will be restarted automatically. 5.
