Red Hat Security Advisory: v8 security update

Notes

Topic
An update for v8 is now available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo) for RHEL 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
V8 is Google's open source JavaScript engine. V8 is written in C++ and is used in Google Chrome, the open source browser from Google. V8 implements ECMAScript as specified in ECMA-262, 3rd edition. Security Fix(es): * An integer-overflow flaw was found in V8's Zone class when allocating new memory (Zone::New() and Zone::NewExpand()). An attacker with the ability to manipulate a large zone could crash the application or, potentially, execute arbitrary code with the application privileges. (CVE-2016-1669)
