1. Summary:

Updated redis packages that fix a security issue are now available for
Red Hat Enterprise Linux OpenStack Platform 6.0.

Red Hat Product Security has rated this update as having Moderate security
impact. A Common Vulnerability Scoring System (CVSS) base score, which

References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux OpenStack Platform 6.0 for RHEL 7 - x86_64

3. Description:

Redis is an advanced key-value store. It is often referred to as a data
structure server because keys can contain strings, hashes, lists, sets, or
sorted sets.

An integer-wraparound flaw leading to a stack-based overflow was found in
Redis. A user with access to run Lua code in a Redis session could possibly
use this flaw to crash the server (denial of service) or gain code
execution outside of the Lua sandbox. (CVE-2015-8080)

All users of redis are advised to upgrade to these updated packages, which
correct this issue.
