Summary
Allows viewing and modifying arbitrary structs as bytes
Details
Affected versions of rgb crate allow viewing and modifying data of any type T wrapped in RGB<T> as bytes,
and do not correctly constrain RGB<T> and other wrapper structures to the types for which it is safe to do so.
Safety violation possible for a type wrapped in RGB<T> and similar wrapper structures:
- If
Tcontains padding, viewing it as bytes may lead to exposure of contents of uninitialized memory. - If
Tcontains a pointer, modifying it as bytes may lead to dereferencing of arbitrary pointers. - Any safety and/or validity invariants for
Tmay be violated.
The issue was resolved by requiring all types wrapped in structures provided by RGB crate to implement an unsafe marker trait.
