Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU77910
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2016-7069
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the way EDNS0 OPT records are handled when parsing responses from a backend. When dnsdist is configured to add EDNS Client Subnet to a query, the response may contain an EDNS0 OPT record that has to be removed before forwarding the response to the initial client.
MitigationUpdate the affected package dnsdist to the latest version.

No. We are not aware of malware exploiting this vulnerability.
2) Cross-site request forgery
EUVDB-ID: #VU38443
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2017-7557
CWE-ID:
CWE-352 - Cross-Site Request Forgery (CSRF)
Exploit availability: No

3) Input validation error
EUVDB-ID: #VU77909
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-14663
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to insufficient validation of user-supplied input when processing DNS queries. A remote attacker can smuggle certain DNS records into the DNS backend and perform spoofing attack. This issue occurs only when either the ‘useClientSubnet’ or the experimental ‘addXPF’ parameters are used when declaring a new backend.
MitigationUpdate the affected package dnsdist to the latest version.
