NVD Description

Note: Versions mentioned in the description apply only to the upstream webkit2gtk package and not the webkit2gtk package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

The UNIX IPC layer in WebKit, including WebKitGTK+ prior to 2.16.3, does not properly validate message size metadata, allowing a compromised secondary process to trigger an integer overflow and subsequent buffer overflow in the UI process. This vulnerability does not affect Apple products.
