Mozilla Firefox prior to 3.0.15 and 3.5.x prior to 3.5.4, and SeaMonkey prior to 2.0, does not properly handle a right-to-left override (aka RLO or U+202E) Unicode character in a download filename, which allows remote malicious users to spoof file extensions via a crafted filename, as demonstrated by displaying a non-executable extension for an executable file.
