Mozilla Firefox Download Filename Spoofing Vulnerability
Publish date: February 15, 2011
Severity: CRITICAL
CVE Identifier: CVE-2009-3376
Advisory Date: FEB 15, 2011
DESCRIPTION
Mozilla Firefox before 3.0.15 and 3.5.x before 3.5.4, and SeaMonkey before 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 attackers to spoof file extensions via a crafted filename, as demonstrated by displaying a non-executable extension for an executable file.
