Nmap 7.99 Denial of Service via Zero-Length TCP Option Packet

Nmap - Integer Underflow in IPv6 Extension Header Parsing

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.

In enableSystemPackageLPw of Settings.java, there is a possible way to prevent location access from working due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

nselibssh2.cc in Nmap 7.70 is subject to a denial of service condition due to a double free when an SSH connection fails, as demonstrated by a leading \n character to ssh-brute.nse or ssh-auth-methods.nse.
