object-oriented programming. It has many features to process text
files and to do system management tasks (as in perl). It is simple,
straight-forward, and extensible.";

version 1.8.7.302-2squeeze2.

For the stable distribution (wheezy), these problems have been fixed in
version 1.8.7.358-7.1+deb7u1.

For the unstable distribution (sid), these problems have been fixed in
version 1.8.7.358-9.

We recommend that you upgrade your ruby1.8 packages.";

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 
William (B.J.) Snow Orvis discovered a vulnerability in the hostname
checking in Ruby's SSL client that could allow man-in-the-middle
attackers to spoof SSL servers via a crafted certificate issued by a
trusted certification authority.

CVE-2013-4164 
Charlie Somerville discovered that Ruby incorrectly handled floating
point number conversion. If an application using Ruby accepted
untrusted input strings and converted them to floating point
numbers, an attacker able to provide such input could cause the
application to crash or, possibly, execute arbitrary code with the
privileges of the application.";
