Subject: ssh_get_info.nasl(12634), debian local checks, environment variables, and pread()

Hello Everyone,

Found a problem in ssh_get_info.nasl(12634) when running local checks on debian.

Specifically line 311:
     buf = pread(cmd:"dpkg", argv:make_list("COLUMNS=160 dpkg", "-l") );

Note the attempt to set the environment variable in argv.

This is not working, so the dpkg output is at system default 80
columns, which is chopping off version numbers of many packages.
(which causes subsequent check failures)

Any ideas how to fix? Doesn't seem that nessus_popen4 has any ability
to set any environment variables.

In light of the inherent security risk of setting arbitrary environs,
perhaps a restricted subset of name/value patterns could be
implemented?
