possible bug in 4.84.3-1 located in clamav-wrapper

[Alexandru Ionica]

Hello,

MailScanner 4.84.3-1 fresh install running on Centos-6 x86_64 .
Running MailScanner --debug-sa i noticed the following:
12:54:12 LibClamAV Error: cli_scanhtml: Can't create temporary directory
/var/spool/MailScanner/incoming/SpamAssassin-Temp/tmp.vWQ4hixN67/clamav-497c230ffa4f39a4779ea7618dd8efa4

/var/spool/MailScanner/incoming/SpamAssassin-Temp/tmp.vWQ4hixN67 is a file
and not a directory so this is why it was caused.

I looked at /usr/lib/MailScanner/clamav-wrapper and changed
TempDir=$(mktemp) || { echo "$0: Cannot make name for temporary dir" >&2;
exit 1; }
to
TempDir=$(mktemp -d --tmpdir=/var/spool/MailScanner/clamav) || { echo "$0:
Cannot make name for temporary dir" >&2; exit 1; }

I presume the --tmpdir wouldn't have been needed but i wanted to also move
it do a different folder.
Anyway the cause seems to be the lack of the -d flag to mktemp so mktemp
creates a file instead of a folder.

After doing the above change i don't see any more errors or warnings from
clamav.

Regards.
