CVE-2009-3376

Mozilla Firefox <3.0.15 & SeaMonkey <2.0 - XSS

Title source: llm
STIX 2.1

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.
