-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0074 -- [Win][Netware][UNIX/Linux] Apache HTTP Server 2.2.8, 2.0.63, 1.3.41 released fixing multiple vulnerabilities 21 January 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Apache 2.2.8 Apache 2.0.63 Apache 1.3.41 Publisher: Apache Operating System: UNIX variants (UNIX, Linux, OSX) Windows Netware Impact: Cross-site Scripting Denial of Service Access: Remote/Unauthenticated CVE Names: CVE-2008-0005 CVE-2007-6422 CVE-2007-6421 CVE-2007-6388 CVE-2007-5000 CVE-2007-3847 Ref: AA-2008.0009 ESB-2008.0056 Original Bulletin: http://httpd.apache.org/security/vulnerabilities_22.html http://www.apache.org/dist/httpd/CHANGES_2.0.63 http://www.apache.org/dist/httpd/CHANGES_1.3.41 Comment: While this advisory primarily relates to Apache 2.2.8, versions 2.0.63 and 1.3.41 have also been released. According to the Apache website, version 2.2.8 also addresses a vulnerability not mentioned in the below advisory: "low: mod_proxy_ftp UTF-7 XSS CVE-2008-0005 A workaround was added in the mod_proxy_ftp module. On sites where mod_proxy_ftp is enabled and a forward proxy is configured, a cross-site scripting attack is possible against Web browsers which do not correctly derive the response character set following the rules in RFC 2616." Version 2.0.63 addresses the vulnerabilities identified below in CVE-2007-6388 and CVE-2007-5000. Version 1.3.41 addresses a separate vulnerability in addition to those mentioned above which is specific to the Windows and Netware platforms: "CVE-2007-3847 (cve.mitre.org) mod_proxy: Prevent reading past the end of a buffer when parsing date-related headers. PR 41144." - --------------------------BEGIN INCLUDED TEXT-------------------- Apache HTTP Server 2.2.8 (2.0.63, 1.3.41) Released The Apache Software Foundation and the Apache HTTP Server Project are pleased to announce the release of version 2.2.8 of the Apache HTTP Server ("Apache"). This version of Apache is principally a bug and security fix release. The following potential security flaws are addressed: * CVE-2007-6421 (cve.mitre.org) mod_proxy_balancer: Correctly escape the worker route and the worker redirect string in the HTML output of the balancer manager. Reported by SecurityReason. A flaw was found in the mod_proxy_balancer module. On sites where mod_proxy_balancer is enabled, a cross-site scripting attack against an authorized user is possible. * CVE-2007-6422 (cve.mitre.org) Prevent crash in balancer manager if invalid balancer name is passed as parameter. Reported by SecurityReason. A flaw was found in the mod_proxy_balancer module. On sites where mod_proxy_balancer is enabled, an authorized user could send a carefully crafted request that would cause the Apache child process handling that request to crash. This could lead to a denial of service if using a threaded Multi-Processing Module. * CVE-2007-6388 (cve.mitre.org) mod_status: Ensure refresh parameter is numeric to prevent a possible XSS attack caused by redirecting to other URLs. Reported by SecurityReason. A flaw was found in the mod_status module. On sites where mod_status is enabled and the status pages were publicly accessible, a cross-site scripting attack is possible. Note that the server-status page is not enabled by default and it is best practice to not make this publicly available. * CVE-2007-5000 (cve.mitre.org) mod_imagemap: Fix a cross-site scripting issue. Reported by JPCERT. A flaw was found in the mod_imap module. On sites where mod_imap is enabled and an imagemap file is publicly available, a cross-site scripting attack is possible. We consider this release to be the best version of Apache available, and encourage users of all prior versions to upgrade. Apache HTTP Server 2.2.8 is available for download from: http://httpd.apache.org/download.cgi Apache 2.2 offers numerous enhancements, improvements, and performance boosts over the 2.0 codebase. For an overview of new features introduced since 2.0 please see: http://httpd.apache.org/docs/2.2/new_features_2_2.html Please see the CHANGES_2.2 file, linked from the download page, for a full list of changes. A condensed list, CHANGES_2.2.8 provides the complete list of changes since 2.2.6 (2.2.7 was not released). A summary of security vulnerabilities which were addressed in the previous 2.2.6 and earlier releases is available: http://httpd.apache.org/security/vulnerabilities_22.html Apache HTTP Server 1.3.41 and 2.0.63 legacy releases are also currently available. See the appropriate CHANGES from the url above. See the corresponding CHANGES files linked from the download page. The Apache HTTP Project developers strongly encourage all users to migrate to Apache 2.2, as only limited maintenance is performed on these legacy versions. This release includes the Apache Portable Runtime (APR) version 1.2.12 bundled with the tar and zip distributions. The APR libraries libapr and libaprutil (and on Win32, libapriconv) must all be updated to ensure binary compatibility and address many known platform bugs. This release builds on and extends the Apache 2.0 API. Modules written for Apache 2.0 will need to be recompiled in order to run with Apache 2.2, and require minimal or no source code changes. http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x/VERSIONING When upgrading or installing this version of Apache, please bear in mind that if you intend to use Apache with one of the threaded MPMs (other than the Prefork MPM), you must ensure that any modules you will be using (and the libraries they depend on) are thread-safe. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
