Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Resource management error

EUVDB-ID: #VU50954

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-2021-22883

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 multiple connection attempts with an 'unknownProtocol'. A remote attacker can initiate multiple connections with the server, which will trigger a leak of file descriptors and result in a denial of service (DoS) condition.

Mitigation

Update the affected package nodejs10 to the latest version.

Vulnerable software versions

SUSE Linux Enterprise Module for Web Scripting: 12

nodejs10-docs: before 10.24.0-1.36.2

npm10: before 10.24.0-1.36.2

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

2) DNS rebinding

EUVDB-ID: #VU50955

Risk: Medium

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

CVE-ID: CVE-2021-22884

CWE-ID: CWE-350 - Reliance on Reverse DNS Resolution for a Security-Critical Action

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DNS rebinding attack.

The vulnerability exists due to the application whitelist includes the “localhost6” name. When “localhost6” is not present in /etc/hosts, it is treated an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain.

Mitigation

Update the affected package nodejs10 to the latest version.

3) Input validation error

EUVDB-ID: #VU50745

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-2021-23840

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 during EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate calls. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

Mitigation

Update the affected package nodejs10 to the latest version.
