NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-hivex package and not the python3-hivex package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

A flaw was found in the hivex library in versions before 1.3.20. It is caused due to a lack of bounds check within the hivex_open function. An attacker could input a specially crafted Windows Registry (hive) file which would cause hivex to read memory beyond its normal bounds or cause the program to crash. The highest threat from this vulnerability is to system availability.
