Description Jan Lieskovsky 2013-08-08 13:32:00 UTC 
A security flaw was found in the way Orca, a screen reader that provides access to the graphical desktop via user-customizable combinations of speech and/or braille, used to load required Python language modules (existing Python module in current working directory with name matching some of the modules Orca required for its run was previously loaded and subsequently used). A local attacker, with ability to write into directory, the victim user was running Orca from, could use this flaw to execute arbitrary code with the privileges of the user running Orca.
