firefox-esr is vulnerable to Code Injection. This vulnerability arises from the use of newline characters in filenames, which could bypass file extension security mechanisms that replace malicious extensions (e.g., .lnk) with .download. This allows an attacker to inject and execute malicious code. This bug only affects Firefox and Thunderbird on Windows
