Mozilla: Use-after-free in XMLHttpRequest
A use-after-free vulnerability can occur when working with XMLHttpRequest (XHR) in an event loop, causing the XHR main thread to be called after it has been freed. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
Statement: In general, this flaw cannot be exploited through email in Thunderbird because scripting is disabled when reading mail, but it is potentially a risk in browser or browser-like contexts.

## Abstract
Memory safety in complex applications implemented in unsafe programming languages such as C/ is still an unresolved problem in practice. Such applications were often developed in an ad-hoc, security-ignorant fashion, and thus they contain many types of security issues.
Many different types of defenses have been proposed in the past to mitigate these problems, some of which are even widely used in practice.
