Email appliacations and file browsers etc. are run as normal users. So, even if the user stupidly run this mysterious program he got in the mail - what happens?
It search for all ELF executables in the system and find it can open none! They are not writeable, and the user don't own them so the bad program cannot change permissions in order to modify the executables either.
About the only "danger" here is messing with a developer's program being developed, but he can recompile it and loose the virus that way. And a developer wouldn't trust a program he got in the mail in the first place. Those dumb enough don't have any writeable executables.
