3. Description:

 

Ruby is an extensible, interpreted, object-oriented, scripting language.

It has features to process text files and to perform system management

tasks.

 

Multiple denial of service flaws were found in the way the Ruby REXML XML

parser performed expansion of parameter entities. A specially crafted XML

document could cause REXML to use an excessive amount of CPU and memory.

(CVE-2014-8080, CVE-2014-8090)

 

A stack-based buffer overflow was found in the implementation of the Ruby

Array pack() method. When performing base64 encoding, a single byte could

be written past the end of the buffer, possibly causing Ruby to crash.

(CVE-2014-4975)

 

The CVE-2014-8090 issue was discovered by Red Hat Product Security.

 

All ruby users are advised to upgrade to these updated packages, which

contain backported patches to correct these issues. All running instances

of Ruby need to be restarted for this update to take effect.

 

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/articles/11258

 

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

 

1118158 - CVE-2014-4975 ruby: off-by-one stack-based buffer overflow in the encodes() function

1157709 - CVE-2014-8080 ruby: REXML billion laughs attack via parameter entity expansion
