Description Doran Moppert 2019-09-04 00:48:58 UTC

Logging-related command line parameters are not properly sanitized when Firefox is launched by another program, such as when a user clicks on malicious links in a chat application. This can be used to write a log file to an arbitrary location such as the Windows 'Startup' folder. 

*Note: this issue only affects Firefox on Windows operating systems.*
