remote code execution in opera

This update upgrades the Opera web browser to the 8.50 release. Besides the changes in 8.50 that are listed in http://www.opera.com/docs/changelogs/linux/850/ following security problems were fixed: 1. Attached files are opened without any warnings directly from the user’s cache directory. This can be exploited to execute arbitrary Javascript in context of “file://”. 2. Normally, filename extensions are determined by the “Content-Type” in Opera Mail. However, by appending an additional ‘.’ to the end of a filename, an HTML file could be spoofed to be e.g. “image.jpg.”. These two vulnerabilities combined may be exploited to conduct script insertion attacks if the user chooses to view an attachment named e.g. “image.jpg.” e.g. resulting in disclosure of local files.

Solution

There is no known workaround, please install the update packages.
