Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 21.04 host has packages installed that are affected by a vulnerability as referenced in the USN-5148-1 advisory.

 - 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. (CVE-2021-3504)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
