Описание
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.

Отчет
The hivex utility being non-privileged, does not handle any confidential information. Any external program using the hivex library could be exposed to partial unavailability in case of a crash where a user can always retry the operation. As for libguestfs, a crash in hivex would not result in libguestfs crashing.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
