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-2015-1243, CVE-2015-1250)

This update also fixes the following bug:

* Prior to this update, Chromium did not accept GNOME's system proxy
settings due to having GConf support disabled. This issue has been resolved
in this update. (BZ#1217065)

All Chromium users should upgrade to these updated packages, which contain
Chromium version 42.0.2311.135, which corrects these issues. After
installing the update, Chromium must be restarted for the changes to take
effect.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
