Malicious software in Windows has been known to try getting past simple
file type checks by spreading a zip file containing the actual
executable.

In our case, a user could get a tarball containing an executable with
the +x bit set from a malicious user.

Perhaps make file-roller ask the user before unpacking archives that
have the executable bit set.

Binary package hint: nautilus

Following the ratification of the "Execute-Permission Bit Required" security policy, several packages need to have their mime handlers updated to reject opening of various file types that are actually executables when they lack the execute bit.
