Description

Apache Tomcat is a servlet container for the Java Servlet and JavaServerPages (JSP) technologies.It was found that when Tomcat processed a series of HTTP requests in whichat least one request contained either multiple content-length headers, orone content-length header with a chunked transfer-encoding header, Tomcatwould incorrectly handle the request. A remote attacker could use this flawto poison a web cache, perform cross-site scripting (XSS) attacks, orobtain sensitive information from other requests. (CVE-2013-4286)It was discovered that the fix for CVE-2012-3544 did not properly resolve adenial of service flaw in the way Tomcat processed chunk extensions andtrailing headers in chunked requests. A remote attacker could use this flawto send an excessively long request that, when processed by Tomcat, couldconsume network bandwidth, CPU, and memory on the Tomcat server. Note thatchunked transfer encoding is enabled by default. (CVE-2013-4322)A denial of service flaw was found in the way Apache Commons FileUploadhandled small-sized buffers used by MultipartStream. A remote attackercould use this flaw to create a malformed Content-Type header for amultipart request, causing JBoss Web to enter an infinite loop whenprocessing such an incoming request. (CVE-2014-0050)All Tomcat users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues. Tomcat must berestarted for this update to take effect.
