Language:

Synopsis

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

Description

The version of OpenEXR installed on the remote host is prior to 1.7.1-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2241 advisory.

There's a flaw in OpenEXR's Scanline API functionality in versions before 3.0.0-beta. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger excessive consumption of memory, resulting in an impact to system availability. (CVE-2021-3479)

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 OpenEXR' to update your system.
