The remote host is missing an update to tomcat5.5 announced via advisory DSA 1468-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201468-1

Several remote vulnerabilities have been discovered in the Tomcat servlet and JSP engine. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2008-0128 Olaf Kock discovered that HTTPS encryption was insufficiently enforced for single-sign-on cookies, which could result in information disclosure. CVE-2007-2450 It was discovered that the Manager and Host Manager web applications performed insufficient input sanitising, which could lead to cross- site scripting. This update also adapts the tomcat5.5-webapps package to the tightened JULI permissions introduced in the previous tomcat5.5 DSA. However, it should be noted, that the tomcat5.5-webapps is for demonstration and documentation purposes only and should not be used for production systems. For the unstable distribution (sid), these problems will be fixed soon. For the stable distribution (etch), these problems have been fixed in version 5.5.20-2etch2. The old stable distribution (sarge) doesn't contain tomcat5.5. We recommend that you upgrade your tomcat5.5 packages.
