Synopsis

Midnight Commander contains several format string errors, buffer overflows and one buffer underflow leading to execution of arbitrary code.

Background

Midnight Commander is a visual console file manager.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-misc/mc	< 4.6.0-r13	>= 4.6.0-r13	All supported architectures
