Is this vulnerability remotely exploitable?

It can be, if a service or application exposes an interface (such as file upload, network protocol, or API) that passes untrusted compressed data into the vulnerable decompression path without prior sanitization or isolation.

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

An attacker typically only needs the ability to supply or influence compressed data that the affected ROOT-based component will decompress (for example, sending crafted files or network payloads). No direct code execution or privileged access is required initially.

What is the safest general fix pattern for this vulnerability class?

The most robust pattern is to use hardened, up-to-date decompression libraries with comprehensive bounds checking, remove or refactor unsafe custom fast paths, and ensure all length/index calculations are validated before buffer access. Ideally, high-risk parsing logic is isolated in low-privilege components.
