are now available for Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having Important
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.

Chromium is an open source web browser, powered by WebKit (Blink).

Several flaws were found in the processing of malformed web content. A
web page containing malicious content could cause Chromium to crash
or, potentially, execute arbitrary code with the privileges of the
user running Chromium. (CVE-2015-1251, CVE-2015-1252, CVE-2015-1253,
CVE-2015-1254, CVE-2015-1255, CVE-2015-1256, CVE-2015-1257,
CVE-2015-1258, CVE-2015-1259, CVE-2015-1260, CVE-2015-1261,
CVE-2015-1262, CVE-2015-1263, CVE-2015-1264, CVE-2015-1265)

All Chromium users should upgrade to these updated packages, which
contain Chromium version 43.0.2357.65, which corrects these issues.
After installing the update, Chromium must be restarted for the
changes to take effect."
