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 or,
potentially, execute arbitrary code with the privileges of the user running
Chromium. (CVE-2014-7923, CVE-2014-7924, CVE-2014-7925, CVE-2014-7926,
CVE-2014-7927, CVE-2014-7928, CVE-2014-7929, CVE-2014-7930, CVE-2014-7931,
CVE-2014-7932, CVE-2014-7933, CVE-2014-7934, CVE-2014-7935, CVE-2014-7936,
CVE-2014-7937, CVE-2014-7938, CVE-2014-7939, CVE-2014-7940, CVE-2014-7941,
