red hat
Calendar Grey November 25, 2013
Dist Redhat Esm H88
Urgent Python security patch for CentOS targets a memory corruption flaw. Update your installations immediately.
Updated ruby packages that fix one security issue are now available for Red Hat Enterprise Linux 6

Solution

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

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.
