The remote host is missing an update for the Debian 'ruby1.8' package(s) announced via the DSA-2809-1 advisory.

Several vulnerabilities have been discovered in the interpreter for the Ruby language. The Common Vulnerabilities and Exposures project identifies the following problems:
CVE-2013-1821
Ben Murphy discovered that unrestricted entity expansion in REXML can lead to a Denial of Service by consuming all host memory.
CVE-2013-4073
