    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
        -------------------------------------------------------------------
      1 app-misc/mc < 4.6.0-r13 >= 4.6.0-r13

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

    Midnight Commander contains several format string vulnerabilities
    (CAN-2004-1004), buffer overflows (CAN-2004-1005), a memory
    deallocation error (CAN-2004-1092) and a buffer underflow
    (CAN-2004-1176).

    Impact
    ======

    An attacker could exploit these vulnerabilities to execute arbitrary
    code with the permissions of the user running Midnight Commander or
    cause Denial of Service by freeing unallocated memory.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Midnight Commander users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=app-misc/mc-4.6.0-r13"
