SUSE update for nodejs8

1) DNS rebinding

EUVDB-ID: #VU50955

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

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 nodejs8 to the latest version.
