New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 3.6
SynopsisAn application installed on the remote Windows host is affected by multiple denial of service vulnerabilities.
DescriptionThe version of Wireshark installed on the remote Windows host is 2.0.x prior to 2.0.10 or 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 (CVE-2017-5597).
- 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 (CVE-2017-5596).
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Wireshark version 2.0.10 / 2.2.4 or later.
