Description
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
T
contains padding, viewing it as bytes may lead to exposure of contents of uninitialized memory.
- If
T
contains a pointer, modifying it as bytes may lead to dereferencing of arbitrary pointers.
- Any safety and/or validity invariants for
T
may be violated.
The issue was resolved by requiring all types wrapped in structures provided by RGB crate to implement an unsafe marker trait.
