USN-7079-1: WebKitGTK vulnerabilities

Releases

• Ubuntu 24.04 LTS
• Ubuntu 22.04 LTS

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.

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

Ubuntu 24.04

• libjavascriptcoregtk-4.1-0 - 2.46.1-0ubuntu0.24.04.1
• libjavascriptcoregtk-6.0-1 - 2.46.1-0ubuntu0.24.04.1
