Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU16169
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-2018-12122
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to the socket is destroyed on the next received chunk when headers are not completely received within this period. A remote attacker can send headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time, consume excessive resources and cause the service to crash.
MitigationInstall update from vendor's website.
Vulnerable software versionsIBM Cloud Transformation Advisor: 1.8.0 - 1.9.1

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) Heap-based buffer overflow
EUVDB-ID: #VU16168
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-2018-12121
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer overflow. A remote attacker can send many requests with the maximum size HTTP header of nearly 80kb/connection in combination with carefully handled completion of those headers, trigger memory corruption and cause the Node.js HTTP server to abort.
MitigationInstall update from vendor's website.

3) Spoofing attack
EUVDB-ID: #VU16170
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-12123
CWE-ID:
CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to conduct spoofing attack on the target system.
The vulnerability exists due to security decisions are made about the URL based on the hostname. A remote attacker can use a mixed case "javascript:" (e.g. "javAscript:") protocol and spoof the hostname when a Node.js application is using url.parse()to determine the URL hostname.
