Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 7 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2021-2206 advisory.

- Mozilla developers Christian Holler, Anny Gakhokidze, Alexandru Michis, Gabriele Svelto reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. (CVE-2021-29967)
