Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) for macOS are affected by a time-of-check time-of-use (TOCTOU) race condition vulnerability that could result in local privilege escalation. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Weakness

The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check.
