Description

Security researcher Ronald Crane reported an underflow found through code inspection. This does not all have a clear mechanism to be exploited through web content but could be vulnerable if a means can be found to trigger it.

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