TITLE

Apache HTTPD 1.3/2.x Range header DoS vulnerability

DESCRIPTION

The byterange filter in the Apache HTTP Server 1.3.x, 2.0.x through 2.0.64, and 2.2.x through 2.2.19 allows remote attackers to cause a denial of service (memory and CPU consumption) via a Range header that expresses multiple overlapping ranges, as exploited in the wild in August 2011, a different vulnerability than CVE-2007-0086. Both the 'Range' header and the 'Range-Request' header are vulnerable. The attack tool causes a significant increase in CPU and memory usage on the server. Apache HTTPD The server has a service disruption (DoS) Vulnerabilities exist. Apache HTTPD The server Range Header and Request-Range There is a problem with header processing, and service operation is interrupted. (DoS) Vulnerabilities exist. Attacks using this vulnerability have been observed. Also, "Apache Killer" The attack tool called is released. Apache The advisory states that: "Background and the 2007 report There are two aspects to this vulnerability. One is new, is Apache specific; and resolved with this server side fix. The other issue is fundamentally a protocol design issue dating back to 2007: http://seclists.org/bugtraq/2007/Jan/83 The contemporary interpretation of the HTTP protocol (currently) requires a server to return multiple (overlapping) ranges; in the order requested. This means that one can request a very large range (e.g. from byte 0- to the end) 100's of times in a single request. Being able to do so is an issue for (probably all) webservers and currently subject of an IETF discussion to change the protocol: http://trac.tools.ietf.org/wg/httpbis/trac/ticket/311 This advisory details a problem with how Apache httpd and its so called internal 'bucket brigades' deal with serving such "valid" request. The problem is that currently such requests internally explode into 100's of large fetches, all of which are kept in memory in an inefficient way. This is being addressed in two ways. By making things more efficient. And by weeding out or simplifying requests deemed too unwieldy."Service disruption by a remote third party (DoS) There is a possibility of being attacked.

Please review the CVE identifiers referenced below for details. Impact ====== A remote attacker might obtain sensitive information, gain privileges, send requests to unintended servers behind proxies, bypass certain security restrictions, obtain the values of HTTPOnly cookies, or cause a Denial of Service in various ways. A local attacker could gain escalated privileges. Workaround ========== There is no known workaround at this time. Resolution ========== All Apache HTTP Server users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/apache-2.2.22-r1" References ========== [ 1 ] CVE-2010-0408 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0408 [ 2 ] CVE-2010-0434 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0434 [ 3 ] CVE-2010-1452 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1452 [ 4 ] CVE-2010-2791 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-2791 [ 5 ] CVE-2011-3192 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3192 [ 6 ] CVE-2011-3348 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3348 [ 7 ] CVE-2011-3368 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3368 [ 8 ] CVE-2011-3607 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3607 [ 9 ] CVE-2011-4317 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4317 [ 10 ] CVE-2012-0021 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0021 [ 11 ] CVE-2012-0031 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0031 [ 12 ] CVE-2012-0053 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0053 [ 13 ] CVE-2012-0883 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0883 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201206-25.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
