Updated chromium-browser packages that fix multiple security issues 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-2015-1271, CVE-2015-1270, CVE-2015-1272, CVE-2015-1273, CVE-2015-1274, CVE-2015-1276, CVE-2015-1277, CVE-2015-1278, CVE-2015-1279, CVE-2015-1281, CVE-2015-1282, CVE-2015-1283, CVE-2015-1284, CVE-2015-1285, CVE-2015-1286, CVE-2015-1287, CVE-2015-1288, CVE-2015-1289, CVE-2015-5605)
