Description

Security researcher Nils reported a use-after-free in nsImageLoadingContent when content script is executed. This could allow for arbitrary code execution.

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.
