How broadly exploitable is this vulnerability?

Exploitability depends on how an application exposes ICC profile processing; if users or remote systems can supply color-managed files that are processed automatically, the issue can be remotely triggerable and potentially lead to code execution.

Does an attacker need local access to exploit this?

Not necessarily. Any remote vector that allows a crafted ICC profile or image (such as file upload, print jobs, or document viewing) to be processed by a vulnerable iccDEV-dependent application could be sufficient.

What is the safest general fix pattern for developers?

Adopt robust ownership semantics for all dynamically allocated objects (e.g., RAII and smart pointers), ensure that freed pointers are not reused, and refactor transformation setup so that hints and related objects have clearly bounded lifetimes.
