"Iida Minehiko discovered that Tomcat did not properly normalise paths.
A remote attacker could send specially crafted requests to the server
and bypass security restrictions, gaining access to sensitive content.
(CVE-2008-5515)

Yoshihito Fukuyama discovered that Tomcat did not properly handle
errors when the Java AJP connector and mod_jk load balancing are used.
A remote attacker could send specially crafted requests containing
invalid headers to the server and cause a temporary denial of service.
(CVE-2009-0033)

D. Matscheko and T. Hackner discovered that Tomcat did not properly
handle malformed URL encoding of passwords when FORM authentication is
used. A remote attacker could exploit this in order to enumerate valid
usernames. (CVE-2009-0580)

Deniz Cevik discovered that Tomcat did not properly escape certain
parameters in the example calendar application which could result in
browsers becoming vulnerable to cross-site scripting attacks when
processing the output. With cross-site scripting vulnerabilities, if a
user were tricked into viewing server output during a crafted server
request, a remote attacker could exploit this to modify the contents,
or steal confidential data (such as passwords), within the same
domain. (CVE-2009-0781)

Philippe Prados discovered that Tomcat allowed web applications to
replace the XML parser used by other web applications. Local users
could exploit this to bypass security restrictions and gain access to
certain sensitive files. (CVE-2009-0783).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
