The remote host is missing an update to phpsysinfo announced via advisory DSA 346-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20346-1

Albert Puigsech Galicia <ripe@7a69ezine.org> reported that phpsysinfo, a web-based program to display status information about the system, contains two vulnerabilities which could allow local files to be read, or arbitrary PHP code to be executed, under the privileges of the web server process (usually www-data). These vulnerabilities require access to a writable directory on the system in order to be exploited. For the stable distribution (woody) this problem has been fixed in version 2.0-3woody1. For the unstable distribution (sid) this problem will be fixed soon. See Debian bug #200543. We recommend that you update your phpsysinfo package.
