Name of the Vulnerable Software and Affected Versions hivex (affected versions not specified)

Description A flaw in the hivex library allows an attacker to input a specially crafted Windows Registry (hive) file. This would cause hivex to recursively call the get children() function, leading to a stack overflow. The highest threat from this issue is to system availability. It is also related to a buffer overflow in memory, which can be exploited to cause a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
