Public bug reported:
Amavis incorrectly assumes that /usr/bin/nvcc is the "Norman virus
control" executable, and attempts to use it to virus check incoming
emails.
In systems with the NVIDIA CUDA compiler installed, the nvcc executable
is actually the CUDA compiler, and so exits with a non-zero (exit) state
every time amavis attempts to execute it on email traffic.
This behavior results in all email traffic being marked (and
quarantined) by amavis as containing a virus whenever NVIDIA CUDA is
installed on the same system as amavisd-new.
The increasing use of gpu acceleration for speeding up and
multithreading particular server processing tasks means that in the
future more servers may experience this problem as they have NVIDIA CUDA
installed on them.
I believe that amavis should verify that nvcc is the Norman virus
control executable prior to attempting to use it as a virus check.
A workaround for this bug on current ubuntu systems is to modify the default
/etc/amavis/conf.d/15-av_scanners file and comment out the following three
lines:
['Norman Virus Control v5 / Linux', 'nvcc',
'-c -l:0 -s -u -temp:$TEMPBASE {}', [0,10,11], [1,2,14],
qr/(?i).* virus in .* -> \'(.+)\'/m ],
