CVE ID : CVE-2013-4164
Debian Bug : 730178

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.

For the oldstable distribution (squeeze), this problem has been fixed in
version 1.9.2.0-2+deb6u2.

For the stable distribution (wheezy), this problem has been fixed in
