was done with the second patch for CVE-2016-10189)

CVE-2016-10189 NULL pointer dereference with file transfer request
from unknown contacts.

CVE-2016-10188 deactivate any incoming file transfer for bitlbee This
affects any libpurple protocol when used through BitlBee. It does not
affect other libpurple-based clients such as pidgin.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
