Description

Security researcher Scott Bell used the Address Sanitizer tool to discover a use-after-free when using a <select> element in a form after it has been destroyed. This could lead to a potentially exploitable crash.

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.
