Synopsis
========

Multiple security issues have been discovered in Midnight Commander
including several buffer overflows and string format vulnerabilities.

Background
==========

Midnight Commander is a visual console file manager.

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

    -------------------------------------------------------------------
     Package      /   Vulnerable   /                        Unaffected
    -------------------------------------------------------------------
  1  app-misc/mc      <= 4.6.0-r6                          >= 4.6.0-r7

Description
===========

Numerous security issues have been discovered in Midnight Commander,
including several buffer overflow vulnerabilities, multiple
vulnerabilities in the handling of temporary file and directory
creation, and multiple format string vulnerabilities.

Impact
======

The buffer overflows and format string vulnerabilites may allow
attackers to cause a denial of service or execute arbitrary code with
permissions of the user running MC. The insecure creation of temporary
files and directories could lead to a privilege escalation, including
root privileges, for a local attacker.

Workaround
==========

There is no known workaround at this time. All users are advised to
upgrade to version 4.6.0-r7 or higher of Midnight Commander.

Resolution
==========

All Midnight Commander users should upgrade to the latest stable
version:

    # emerge sync

    # emerge -pv ">=app-misc/mc-4.6.0-r7
    # emerge ">=app-misc/mc-4.6.0-r7"
