Ubuntu Several security issues were fixed in Ruby.
==========================================================================
Ubuntu Security Notice USN-1733-1
February 21, 2013

ruby1.9.1 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Ruby.

Software Description:
- ruby1.9.1: Interpreter of object-oriented scripting language Ruby

Details:

Jean-Philippe Aumasson discovered that Ruby incorrectly generated
predictable hash values. An attacker could use this issue to generate hash
collisions and cause a denial of service. (CVE-2012-5371)

Evgeny Ermakov discovered that documentation generated by rdoc is
vulnerable to a cross-site scripting issue. With cross-site scripting
vulnerabilities, if a user were tricked into viewing a specially crafted
page, a remote attacker could exploit this to modify the contents, or steal
confidential data, within the same domain. (CVE-2013-0256)

Thomas Hollstegge and Ben Murphy discovered that the JSON implementation
in Ruby incorrectly handled certain crafted documents. An attacker could
use this issue to cause a denial of service or bypass certain protection
mechanisms. (CVE-2013-0269)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.10:
  libruby1.9.1                    1.9.3.194-1ubuntu1.3
  ruby1.9.1                       1.9.3.194-1ubuntu1.3

Ubuntu 12.04 LTS:
  libruby1.9.1                    1.9.3.0-1ubuntu2.5
  ruby1.9.1                       1.9.3.0-1ubuntu2.5

In general, a standard system update will make all the necessary changes.
