code.

Background
==========

Midnight Commander is a visual console file manager.

Affected packages
=================

deallocation error (CAN-2004-1092) and a buffer underflow
(CAN-2004-1176).

code with the permissions of the user running Midnight Commander or
cause Denial of Service by freeing unallocated memory.

Workaround
