Detail
Problem Description: 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 Important. 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) - 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. Description: The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. Security Fix(es): * It was discovered that httpd used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request. (CVE-2016-5387) Note: After this update, httpd will no longer pass the value of the Proxy request header to scripts via the HTTP_PROXY environment variable. Red Hat would like to thank Scott Geary (VendHQ) for reporting this issue. Bug Fix(es): * In a caching proxy configuration, the mod_cache module would treat content as stale if the Expires header changed when refreshing a cached response. As a consequence, an origin server returning content without a fixed Expires header would not be treated as cacheable. The mod_cache module has been fixed to ignore changes in the Expires header when refreshing content. As a result, such content is now cacheable, improving performance and reducing load at the origin server. (BZ#1347648) * The HTTP status code 451 "Unavailable For Legal Reasons" was not usable in the httpd configuration. As a consequence, modules such as mod_rewrite could not be configured to return a 451 error if required for legal purposes. The 451 status code has been added to the list of available error codes, and modules can now be configured to return a 451 error if required. (BZ#1353269) 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. Bugs fixed (https://bugzilla.redhat.com/): 1347648 - Apache can not cache content if Expires header is modified 1353269 - Support sending http 451 status code from RewriteRule 1353755 - CVE-2016-5387 Apache HTTPD: sets environmental variable based on user supplied Proxy request header |
