CVE-2020-13558

A code execution vulnerability exists in the AudioSourceProviderGStreamer functionality of Webkit WebKitGTK 2.30.1. A specially crafted web page can lead to a use after free.

GNOME is the default desktop environment of Rocky Linux.

The following packages have been upgraded to a later upstream version: gdm (40.0), webkit2gtk3 (2.32.3). (BZ#1909300)
