"This updates fixes a potential integer overflow in option parsing.

A user in the group 'dip' could provide a specially crafted
configuration file of more than 2G and generate an integer overflow.
This may enable an attacker to overwrite the heap and thereby corrupt
security-relevant variables.

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