Description

Security researcher Nils used the Address Sanitizer to discover a use-after-free problem when the Document Object Model is modified during a SetBody mutation event. This causes a potentially exploitable crash.

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