Tomcat 全系报 DoS 拒绝服务和信息暴露漏洞，包括：
CVE-2014-0075 Denial of Service Severity: Important Vendor: The Apache Software Foundation Versions Affected: - Apache Tomcat 8.0.0-RC1 to 8.0.3 - Apache Tomcat 7.0.0 to 7.0.52 - Apache Tomcat 6.0.0 to 6.0.39 Description: It was possible to craft a malformed chunk size as part of a chucked request that enabled an unlimited amount of data to be streamed to the server, bypassing the various size limits enforced on a request. This enabled a denial of service attack. Mitigation: Users of affected versions should apply one of the following mitigations - Upgrade to Apache Tomcat 8.0.5 or later (8.0.4 contains the fix but was not released) - Upgrade to Apache Tomcat 7.0.53 or later - Upgrade to Apache Tomcat 6.0.41 or later (6.0.40 contains the fix but was not released) CVE-2014-0095 Denial of Service Severity: Important Vendor: The Apache Software Foundation Versions Affected: - Apache Tomcat 8.0.0-RC2 to 8.0.3 Description: A regression was introduced in revision 1519838 that caused AJP requests to hang if an explicit content length of zero was set on the request. The hanging request consumed a request processing thread which could lead to a denial of service. Mitigation: Users of affected versions should apply one of the following mitigations - Upgrade to Apache Tomcat 8.0.5 or later (8.0.4 contains the fix but was not released) CVE-2014-0096 Information Disclosure Severity: Important Vendor: The Apache Software Foundation Versions Affected: - Apache Tomcat 8.0.0-RC1 to 8.0.3 - Apache Tomcat 7.0.0 to 7.0.52 - Apache Tomcat 6.0.0 to 6.0.39 Description: The default servlet allows web applications to define (at multiple levels) an XSLT to be used to format a directory listing. When running under a security manager, the processing of these was not subject to the same constraints as the web application. This enabled a malicious web application to bypass the file access constraints imposed by the security manager via the use of external XML entities. Mitigation: Users of affected versions should apply one of the following mitigations - Upgrade to Apache Tomcat 8.0.5 or later (8.0.4 contains the fix but was not released) - Upgrade to Apache Tomcat 7.0.53 or later - Upgrade to Apache Tomcat 6.0.41 or later (6.0.40 contains the fix but was not released) CVE-2014-0097 Information Disclosure Severity: Important Vendor: The Apache Software Foundation Versions Affected: - Apache Tomcat 8.0.0-RC1 to 8.0.3 - Apache Tomcat 7.0.0 to 7.0.52 - Apache Tomcat 6.0.0 to 6.0.39 Description: The code used to parse the request content length header did not check for overflow in the result. This exposed a request smuggling vulnerability when Tomcat was located behind a reverse proxy that correctly processed the content length header. Mitigation: Users of affected versions should apply one of the following mitigations - Upgrade to Apache Tomcat 8.0.5 or later (8.0.4 contains the fix but was not released) - Upgrade to Apache Tomcat 7.0.53 or later - Upgrade to Apache Tomcat 6.0.41 or later (6.0.40 contains the fix but was not released) CVE-2014-0119 Information Disclosure Severity: Important Vendor: The Apache Software Foundation Versions Affected: - Apache Tomcat 8.0.0-RC1 to 8.0.5 - Apache Tomcat 7.0.0 to 7.0.53 - Apache Tomcat 6.0.0 to 6.0.39 Description: In limited circumstances it was possible for a malicious web application to replace the XML parsers used by Tomcat to process XSLTs for the default servlet, JSP documents, tag library descriptors (TLDs) and tag plugin configuration files. The injected XMl parser(s) could then bypass the limits imposed on XML external entities and/or have visibility of the XML files processed for other web applications deployed on the same Tomcat instance. Mitigation: Users of affected versions should apply one of the following mitigations - Upgrade to Apache Tomcat 8.0.8 or later (8.0.6 and 8.0.7 contain the fix but were not released) - Upgrade to Apache Tomcat 7.0.54 or later - Upgrade to Apache Tomcat 6.0.41 or later (6.0.40 contains the fix but was not released)在 Ubuntu 12.04 LTS 上通过 Tomcat 部署 Solr 4
