Red Hat 6.X: RHSA-2013:1767-01 Critical: Ruby Buffer Overflow

red hat
Calendar Grey November 26, 2013
Dist Redhat Esm H88
A crucial alert for Ruby in Red Hat Enterprise Linux highlights a security vulnerability due to a buffer overflow. It is imperative to update your packages without delay.
Updated ruby packages that fix one security issue are now available for Red Hat Enterprise Linux 6.2, 6.3, and 6.4 Extended Update Support

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

Summary

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.
