Description Doran Moppert 2020-02-11 22:41:52 UTC
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.*
