Red Hat Security Advisory 2013-1767-01
Posted Nov 27, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-1767-01 - Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to perform system management tasks. A buffer overflow flaw was found in the way Ruby parsed floating point numbers from their text representation. 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.

3. Description:

Ruby is an extensible, interpreted, object-oriented, scripting language.
It has features to process text files and to perform system management
tasks.

A buffer overflow flaw was found in the way Ruby parsed floating point
numbers from their text representation. 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. (CVE-2013-4164)

All ruby users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1033460 - CVE-2013-4164 ruby: heap overflow in floating point parsing
