Description
Nmap 7.70 contains a denial of service vulnerability that allows local attackers to crash the application by processing malicious XML files with exponential entity expansion. Attackers can create a crafted XML file with nested entity definitions and open it through ZenMap's scan import functionality to cause the program to consume excessive system resources and crash.
