Is this vulnerability remotely exploitable?

It can be, if an application using iccDEV accepts ICC profiles or related media from remote users (for example, through file uploads, document imports, or remote resources). In that case, a crafted file delivered over the network could trigger the issue during parsing.

What level of access does an attacker need to exploit this?

An attacker needs the ability to cause the vulnerable application to parse a malicious ICC profile or associated text. This typically means upload or import permissions, or control over content that the application automatically processes (such as images or documents with embedded profiles).

What is the safest general fix pattern?

Strengthen input validation and bounds checking around parsing routines, ensuring that buffer sizes are always checked against input lengths before writes occur. Additionally, favor safe memory handling abstractions and clear limits on profile sizes and array dimensions.
