Summary

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.
