Description Andrej Nemec 2017-07-20 12:11:40 UTC

gnome-exe-thumbnailer before 0.9.5 is prone to a VBScript Injection when generating thumbnails for MSI files, aka the "Bad Taste" issue. There is a local attack if the victim uses the GNOME Files file manager, and navigates to a directory containing a .msi file with VBScript code in its filename.

Statement:

This issue did not affect any of the Red Hat products as they did not include the gnome-exe-thumbnailer package.
