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 ruby200-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.
