USN-5522-1: WebKitGTK vulnerabilities

18 July 2022

Several security issues were fixed in WebKitGTK.



  • webkit2gtk - Web content engine library for GTK+


Several security issues were discovered in 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

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

Ubuntu 22.04
Ubuntu 20.04

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.
