3. Description:

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, execute
arbitrary code, or disclose sensitive information when visited by the
victim. (CVE-2016-1612, CVE-2016-1613, CVE-2016-1614, CVE-2016-1615,
CVE-2016-1616, CVE-2016-1617, CVE-2016-1618, CVE-2016-1619, CVE-2016-1620,
CVE-2016-2051, CVE-2016-2052)

All Chromium users should upgrade to these updated packages, which
contain Chromium version 48.0.2564.82, which corrects these issues.
After installing the update, Chromium must be restarted for the changes
to take effect.
