USN-6545-1: WebKitGTK vulnerabilities

Packages

webkit2gtk - Web content engine library for GTK+

Details

Several security issues were discovered in the WebKitGTK Web and JavaScript
engines. If a user were tricked into viewing a malicious website, a remote
attacker could exploit a variety of issues related to web browser security,
including cross-site scripting attacks, denial of service attacks, and
arbitrary code execution.

Update instructions

This update uses a new upstream release, which includes additional bug fixes. After a standard system update you need to restart any applications that use WebKitGTK, such as Epiphany, to make all the necessary changes.
