The remote host is missing an update to libapache2-mod-fcgid announced via advisory DSA 2436-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%202436-1

It was discovered that the Apache FCGID module, a FastCGI implementation, did not properly enforce the FcgidMaxProcessesPerClass resource limit, rendering this control ineffective and potentially allowing a virtual host to consume excessive resources. For the stable distribution (squeeze), this problem has been fixed in version 1:2.3.6-1+squeeze1. For the testing distribution (wheezy), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 1:2.3.6-1.1. We recommend that you upgrade your libapache2-mod-fcgid packages.
