Detailed Description The version of Wireshark installed on the remote Windows host is 2.2.x prior to 2.2.4. It is, therefore, affected by multiple denial of service vulnerabilities :

- A denial of service vulnerability exists when handling DHCPv6 packets due to an integer overflow condition in file epan/dissectors/packet-dhcpv6.c. An unauthenticated, remote attacker can exploit this to cause the program to enter a large loop that consumes excessive CPU resources. (VulnDB 150784)

- A denial of service vulnerability exists in the asterix_fspec_len() function within file epan/dissectors/packet-asterix.c due to an infinite loop flaw that is triggered because certain input is improperly validated. An unauthenticated, remote
attacker can exploit this to consume excessive CPU resources. (VulnDB 150785)

* Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of this condition will result in the check not being performed and a False Negative for all vulnerable hosts.
