Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Resource management error

EUVDB-ID: #VU67545

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-2022-2795

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

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

The vulnerability exists due to improper management of internal resources within the application when processing large delegations. A remote attacker can flood the target resolver with queries and perform a denial of service (DoS) attack.

Mitigation

Update the affected package bind to the latest version.

No. We are not aware of malware exploiting this vulnerability.

2) Memory leak

EUVDB-ID: #VU67549

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-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.

Mitigation

Update the affected package bind to the latest version.
