From https://bugzilla.redhat.com/show_bug.cgi?id=1102038: It was found that 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. Tomcat 6 fix (3 patches): http://svn.apache.org/viewvc?view=revision&revision=1589640 http://svn.apache.org/viewvc?view=revision&revision=1593815 http://svn.apache.org/viewvc?view=revision&revision=1593821 Tomcat 7 fix (4 patches): http://svn.apache.org/viewvc?view=revision&revision=1588199 http://svn.apache.org/viewvc?view=revision&revision=1589997 http://svn.apache.org/viewvc?view=revision&revision=1590028 http://svn.apache.org/viewvc?view=revision&revision=1590036 From https://bugzilla.redhat.com/show_bug.cgi?id=1102030: It was found that 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. Tomcat 6 fix: http://svn.apache.org/viewvc?view=revision&revision=1580473 Tomcat 7 fix: http://svn.apache.org/viewvc?view=revision&revision=1578814 @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Adding some more vulnerabilities and CVE's. Fixed in following versions as per URL upstream: http://tomcat.apache.org/security-7.html Fixed in Apache Tomcat 7.0.53 CVE-2014-0075, CVE-2014-0096, CVE-2014-0099 Fixed in Apache Tomcat 7.0.54 CVE-2014-0119 Maintainer(s): after the bump please let us know when the ebuild is ready for stabilization.
CVE-2014-0119 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0119): Apache Tomcat before 6.0.40, 7.x before 7.0.54, and 8.x before 8.0.6 does not properly constrain the class loader that accesses the XML parser used with an XSLT stylesheet, which allows remote attackers to (1) read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue, or (2) read files associated with different web applications on a single Tomcat instance via a crafted web application. CVE-2014-0099 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0099): Integer overflow in java/org/apache/tomcat/util/buf/Ascii.java in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4, when operated behind a reverse proxy, allows remote attackers to conduct HTTP request smuggling attacks via a crafted Content-Length HTTP header. CVE-2014-0096 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0096): java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 does not properly restrict XSLT stylesheets, which allows remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue. CVE-2014-0075 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0075): Integer overflow in the parseChunkHeader function in java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 allows remote attackers to cause a denial of service (resource consumption) via a malformed chunk size in chunked transfer coding of a request during the streaming of data.
Just committed tomcat-6.0.41 and tomcat-7.0.56.
