Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 06061c59-f212-11f0-9ca3-b42e991fc52e advisory.

 Incorrect boundary conditions in the Graphics component.
 Use-after-free in the IPC component.
 Sandbox escape due to integer overflow in the Graphics component.
 Sandbox escape due to incorrect boundary conditions in the Graphics component.
 Mitigation bypass in the DOM: Security component.

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

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

Solution

Update the affected packages.
