Summary

Several security issues were fixed in WebKitGTK+.

Software Description

• webkit2gtk - Web content engine library for GTK+

Details

A large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines.

The problem can be corrected by updating your system to the following package versions:
