USN-3640-1: WebKitGTK+ vulnerability

8 May 2018

A security issue was fixed in WebKitGTK+.



  • webkit2gtk - Web content engine library for GTK+


Ivan Fratric discovered that WebKitGTK+ incorrectly handled certain web
content. If a user were tricked into viewing a malicious website, a remote
attacker could possibly exploit this to execute arbitrary code.

Update instructions

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

Ubuntu 18.04
Ubuntu 17.10
Ubuntu 16.04

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.
