Debian: Security update for Tomcat 6

Several vulnerabilities have been found in Tomcat, a servlet and JSP engine. The HTTP Digest Access Authentication implementation performed insufficient countermeasures against replay attacks. In rare setups passwords were written into a logfile. Missing input sanisiting in the HTTP APR or HTTP NIO connectors could lead to denial of service.

AJP requests could be spoofed in some setups. Incorrect request caching could lead to information disclosure. This update also adds countermeasures against a collision denial of service vulnerability in the Java hashtable implementation and addresses denial of service potentials when processing large amounts of requests.

Updated packages are available from security.debian.org.
