Jiri Horner discovered a way to cause xdg-open, a tool that automatically opens URLs in a user’s preferred application, to execute arbitrary commands remotely.

This problem only affects /bin/sh implementations that don’t sanitize local variables. Dash, which is the default /bin/sh in Debian is affected. Bash as /bin/sh is known to be unaffected.
