Description

Security researcher Nils reported two potentially exploitable memory corruption bugs involving scrolling. The first was a use-after-free condition due to scrolling an image document. The second was due to nodes in a range request being added as children of two different parents.

In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled, but are potentially a risk in browser or browser-like contexts.
