Description Jan Lieskovsky 2012-10-03 15:29:03 UTC
A security flaw was found in the way Midnight Commander, a user-friendly text console file manager and visual shell, performed sanitization of MC_EXT_SELECTED environment variable when multiple files were selected (first selected file was used as actual content of the MC_EXT_SELECTED variable, while the remaining files were provided as arguments to the temporary script, handling the F3 / Enter key press event). A remote attacker could provide a specially-crafted archive that, when expanded and previewed by the victim could lead to arbitrary code execution with the privileges of the user running mc executable.
