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:10 relevant fixed versions and status.

A flaw was found in hivex. By supplying a specially crafted Windows registry hive file, an attacker can trigger an out-of-bounds memory read when hivex parses registry values containing malformed large data block lists. This issue can cause the application processing the registry file to crash, resulting in a Denial of Service (DoS).
