- Summary
- Out of bounds access in rgb
- 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 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.
