A CVSS v3 base score of 9.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H). An issue was discovered in Treck IPv6. An out-of-bound read in the DHCPv6 client component may allow an unauthenticated user to cause a possible denial-of-service via adjacent network access.CVE-2020-27338 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H). Improper input validation in the IPv6 component may allow an unauthenticated user to cause an out-of-bounds read of up to three bytes via network access.CVE-2020-27336 has been assigned to this vulnerability. A CVSS v3 base score of 3.7 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).
