Package        : tomcat
Vulnerability  : information exposure, cross site scripting
Problem-Type   : remote
Debian-specific: no
CVE Id         : CAN-2003-0042 CAN-2003-0043 CAN-2003-0044

The developers of tomcat discovered several problems in tomcat version
3.x.  The Common Vulnerabilities and Exposures project identifies the
following problems:

 . CAN-2003-0042: A maliciously crafted request could return a
   directory listing even when an index.html, index.jsp, or other
   welcome file is present.  File contents can be returned as well.

 . CAN-2003-0043: A malicious web application could read the contents
   of some files outside the web application via its web.xml file in
   spite of the presence of a security manager.  The content of files
   that can be read as part of an XML document would be accessible.

 . CAN-2003-0044: A cross-site scripting vulnerability was discovered
   in the included sample web application that allows remote attackers
   to execute arbitrary script code.

For the stable distribution (woody) this problem has been fixed in
version 3.3a-4.1.

The old stable distribution (potato) does not contain tomcat packages.

For the unstable distribution (sid) this problem has been fixed in
version 3.3.1a-1.

We recommend that you upgrade your tomcat package.
