USN-4648-1: WebKitGTK vulnerabilities
26 November 2020
Several security issues were fixed in WebKitGTK.
Releases
Packages
- webkit2gtk - Web content engine library for GTK+
Details
A large number of 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.
