Integer underflow in the add_pseudoheader function in dnsmasq before 2.78 , when the –add-mac, –add-cpe-id or –add-subnet option is specified, allows remote attackers to cause a denial of service via a crafted DNS request.

Weakness

The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
