Detail

Problem Description:

Updated ruby200-ruby packages that fix three security issues are now available for Red Hat Software Collections 1.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Software Collections 1 for Red Hat Enterprise Linux Server (v. 6) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Server (v. 7) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Server EUS (v. 6.4) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Server EUS (v. 6.5) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Server EUS (v. 6.6) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Workstation (v. 6) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64

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 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.

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 1159927 - CVE-2014-8090 ruby: REXML incomplete fix for CVE-2014-8080
