 |
|
hello,
my amavisd-new suddenly blocks exe-files in zips.
it worked fine some time ago.
this is my banned_filename_re:
| Code: |
$banned_filename_re = new_RE(
### BLOCKED ANYWHERE
# qr'^UNDECIPHERABLE$', # is or contains any undecipherable components
qr'^\.(exe-ms|dll)$', # banned file(1) types, rudimentary
# qr'^\.(exe|lha|tnef|cab|dll)$', # banned file(1) types
### BLOCK THE FOLLOWING, EXCEPT WITHIN UNIX ARCHIVES:
# [ qr'^\.(gz|bz2)$' => 0 ], # allow any in gzip or bzip2
[ qr'^\.(rpm|cpio|tar)$' => 0 ], # allow any in Unix-type archives
qr'.\.(pif|scr)$'i, # banned extensions - rudimentary
### BLOCK THE FOLLOWING, EXCEPT WITHIN ARCHIVES:
[ qr'^\.(zip|rar|arc|arj|zoo)$'=> 0 ], # allow any within these archives
qr'^application/x-msdownload$'i, # block these MIME types
qr'^application/x-msdos-program$'i,
qr'^application/hta$'i,
# Windows Metafile file(1) type
# block certain double extensions in filenames
qr'\.[^./]*[A-Za-z][^./]*\.\s*(exe|vbs|pif|scr|bat|cmd|com|cpl|dll)[.\s]*$'i,
qr'.\.(ade|adp|app|bas|bat|chm|cmd|com|cpl|crt|emf|exe|fxp|grp|hlp|hta|
inf|ins|isp|js|jse|lnk|mda|mdb|mde|mdw|mdt|mdz|msc|msi|msp|mst|
ops|pcd|pif|prg|reg|scr|sct|shb|shs|vb|vbe|vbs|
wmf|wsc|wsf|wsh)$'ix, # banned ext - long
);
|
where is the error?
my amavisd-new version is 2.6.1-r1.
i don't know exactly when this error first occured, but i testet it some time ago without problems
sincerely,
kutte128

from what i can see...and i may be wrong
| Code: |
qr'^\.(exe-ms|dll)$', # banned file(1) types, rudimentary

amavisd-new *does* unpack archives, so I'd imagine there's a fair chance it's unpacking the archive, passing the exe to `file`, and blocking.
should move that down to 'block except within archive'
that's my only guess. hope it's right! |

i commented out that entry and now it seems working again.
amavis blocks all .exe and allows them in zips again |
