Cross-site scripting (XSS) vulnerability in certain applications using Apache Tomcat 4.0.0 through 4.0.6 and 4.1.0 through 4.1.34 allows remote attackers to inject arbitrary web script or HTML via crafted "Accept-Language headers that do not conform to RFC 2616".

Cross-site scripting (XSS) vulnerability in the calendar application example in Apache Tomcat 4.0.0 through 4.0.6, 4.1.0 through 4.1.31, 5.0.0 through 5.0.30, and 5.5.0 through 5.5.15 allows remote attackers to inject arbitrary web script or HTML via the time parameter to cal2.jsp and possibly unspecified other vectors. NOTE: this may be related to CVE-2006-0254.1.

The Catalina org.apache.catalina.connector.http package in Tomcat 4.0.x up to 4.0.3 allows remote attackers to cause a denial of service via several requests that do not follow the HTTP protocol, which causes Tomcat to reject later requests.

Tomcat 4.0 through 4.1.12, using mod_jk 1.2.1 module on Apache 1.3 through 1.3.27, allows remote attackers to cause a denial of service (desynchronized communications) via an HTTP GET request with a Transfer-Encoding chunked field with invalid values.
