2) Input validation error

EUVDB-ID: #VU67548

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3080

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error when resolvers are configured to answer from stale cache with zero stale-answer-client-timeout and there is a stale CNAME in the cache for an incoming query. A remote attacker can send a specially crafted request to the DNS resolver and perform a denial of service (DoS) attack.

4) Input validation error

EUVDB-ID: #VU71749

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3488

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of repeated responses to the same query, where both responses contain ECS pseudo-options, however the first is incorrect and gets rejected by the resolver. A remote attacker controlling a malicious nameserver can respond with two responses in quick succession, each with a "CLIENT-SUBNET" pseudo-option and crash the server.

5) Input validation error

EUVDB-ID: #VU71530

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3736

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send specially crafted RRSIG query to the DNS server and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that stale cache and stale answers are enabled, option stale-answer-client-timeout is set to a positive integer, and the resolver receives an RRSIG query.

6) Memory leak

EUVDB-ID: #VU67549

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-38177

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in the DNSSEC verification code for the ECDSA algorithm. A remote attacker can spoof the target resolver with responses that have a malformed ECDSA signature and perform denial of service attack.
