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-2015-6764, CVE-2015-6765, CVE-2015-6766, CVE-2015-6767,
CVE-2015-6768, CVE-2015-6769, CVE-2015-6770, CVE-2015-6771, CVE-2015-6772,

CVE-2015-6778, CVE-2015-6779, CVE-2015-6780, CVE-2015-6781, CVE-2015-6782,
CVE-2015-6784, CVE-2015-6785, CVE-2015-6786, CVE-2015-6787)

All Chromium users should upgrade to these updated packages, which contain
