Midnight Commander is a visual console file manager.
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).
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.
There is no known workaround at this time.
All Midnight Commander users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-misc/mc-4.6.0-r13"
