Multiple memory safety issues in actix-web
Affected versions contain multiple memory safety issues, such as:
- Unsoundly coercing immutable references to mutable references
- Unsoundly extending lifetimes of strings
- Adding the
Sendmarker trait to objects that cannot be safely sent between threads
This may result in a variety of memory corruption scenarios, most likely use-after-free.
A signficant refactoring effort has been conducted to resolve these issues.
