トピック

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 Critical 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.

説明

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-2014-3188, CVE-2014-3189, CVE-2014-3190, CVE-2014-3191,
CVE-2014-3192, CVE-2014-3193, CVE-2014-3194, CVE-2014-3199, CVE-2014-3200)

Several information leak flaws were found in the processing of malformed
web content. A web page containing malicious content could cause Chromium
to disclose potentially sensitive information. (CVE-2014-3195,
CVE-2014-3197, CVE-2014-3198)

All Chromium users should upgrade to these updated packages, which contain
Chromium version 38.0.2125.101, which corrects these issues. After
installing the update, Chromium must be restarted for the changes to take
effect.
