Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper input validation
EUVDB-ID: #VU13376
Risk: Low
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-2018-7161
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to a cleanup bug where objects are used in native code after they are no longer available when the affected software interacts with an HTTP/2 server. A remote attacker can send a specially crafted request that submits malicious input to the targeted node server that provides an HTTP/2 server and cause the node server to crash.
MitigationUpdate to version 10.4.1.
Node.js: 8.0.0 - 10.4.0

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Improper input validation
EUVDB-ID: #VU13379
Risk: Low
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-2018-7167
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can supply Calling Buffer.fill() or Buffer.alloc() with some parameters and cause the server to hang.
MitigationUpdate to version 10.4.1.
Node.js: 6.0.0 - 10.4.0

3) Resource exhaustion
EUVDB-ID: #VU13378
Risk: Low
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-2018-7164
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to insufficient input validation when reading from the network into JavaScript using the net.Socket object directly as a stream. A remote attacker can send tiny chunks of data in short succession, trigger resource exhaustion and cause the server to crash.
MitigationUpdate to version 10.4.1.
Node.js: 9.0.0 - 10.4.0
