Amazon Linux 2 : hivex (ALAS-2021-1717)

medium Nessus Plugin ID 154895

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of hivex installed on the remote host is prior to 1.3.10-6.12. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1717 advisory.

 A flaw was found in the hivex library. This flaw allows an attacker to input a specially crafted Windows Registry (hive) file, which would cause hivex to recursively call the _get_children() function, leading to a stack overflow. The highest threat from this vulnerability is to system availability. (CVE-2021-3622)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update hivex' to update your system.
