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

Critical Nessus Plugin ID 78016


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


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.


Update the affected packages.
