By downloading a file with the .fileloc extension, a semi-privileged
extension could launch an arbitrary application on the user’s computer. The
attacker is restricted as they are unable to download non-quarantined files
or supply command line arguments to the application, limiting the impact.
Note: this issue only occurs on Mac OSX. Other operating systems are
unaffected. This vulnerability affects Thunderbird < 68.5, Firefox < 73,
and Firefox < ESR68.5.
