CVE-2012-3544: Input Validation
First published: Fri May 10 2013(Updated: )
A denial of service flaw was found in the way chunked transfer encoding input filter of Apache Tomcat, an Apache Servlet/JSP Engine, processed CRLF sequences at the end of data chunks in certain circumstances. When the chunked transfer encoding was enabled, a remote attacker could issue a specially-crafted request that, when processed would lead to (limited) denial of service of the Apache Tomcat server. Relevant upstream patch: * for Apache Tomcat 6.x: <a href="http://svn.apache.org/viewvc?view=revision&revision=1476592">http://svn.apache.org/viewvc?view=revision&revision=1476592</a> * for Apache Tomcat 7:x: <a href="http://svn.apache.org/viewvc?view=rev&rev=1378702">http://svn.apache.org/viewvc?view=rev&rev=1378702</a> <a href="http://svn.apache.org/viewvc?view=rev&rev=1378921">http://svn.apache.org/viewvc?view=rev&rev=1378921</a>
