FreeBSD : bash -- remote code execution (512d1301-49b9-11e4-ae2c-c80aa9043978) (Shellshock)

critical Nessus Plugin ID 78016
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Note that this is different than the public 'Shellshock' issue.

Specially crafted environment variables could lead to remote arbitrary code execution. This was fixed in bash 4.3.27, however the port was patched with a mitigation in 4.3.25_2.

Solution

Update the affected packages.
