Synopsis
Critical: ruby security update
Type/Severity
Security Advisory: Critical
Topic
Updated ruby packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having critical
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
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.
Solution
Before applying this update, make sure all previously released errata
