Summary

USN-3781-1 introduced a regression in WebKitGTK+.

Software Description:

- 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.
