Possibly:
$banned_filename_re = new_RE(
# block certain double extensions anywhere in the base
name
qr'.[^./]*[A-Za-z][^./]*.(exe|vbs|pif|scr|bat|cmd|com|cpl|
dll).?$'i,
[ qr'^.(Z|gz|bz2)$' => 0 ], # allow any in
Unix-compressed
[ qr'^.(rpm|cpio|tar)$' => 0 ], # allow any in
Unix-type archives
[ qr'^.(zip|rar|arc|arj|zoo)$'=> 0 ], # allow any
within such archives
[ qr'..(iso|cue|bin)$'i => 0 ], # allow these
extensions
qr'^application/x-msdownload$'i, # block
these MIME types
qr'^application/x-msdos-program$'i,
qr'^application/hta$'i,
qr'..(ade|adp|app|bas|bat|chm|cmd|com|cpl|crt|emf|exe|fxp|
