Red Hat Security Advisory 2016-0097-01 – 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 or gain code execution outside of the Lua sandbox. All users of redis are advised to upgrade to these updated packages, which correct this issue.
