Application Developer for WebSphere Software has addressed the applicable
CVEs.
Vulnerability Details
CVEID: CVE-2018-0734
Description: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a timing side channel attack in the DSA signature
algorithm. An attacker could exploit this vulnerability using variations in
the signing algorithm to recover the private key.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152085 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2018-0735
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a timing side channel attack in the ECDSA signature
algorithm. An attacker could exploit this vulnerability using variations in
the signing algorithm to recover the private key.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
133784 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVE-ID: CVE-2018-5407
Description: Multiple SMT/Hyper-Threading architectures and processors could
allow a local attacker to obtain sensitive information, caused by execution
engine sharing on Simultaneous Multithreading (SMT) architecture. By using the
PortSmash new side-channel attack, an attacker could run a malicious process
next to legitimate processes using the architectur's parallel thread running
capabilities to leak encrypted data from the CPU's internal processes. Note:
This vulnerability is known as PortSmash.
CVSS Base Score: 5.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152484 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVE-ID: CVE-2018-12116
Description: Node.js is vulnerable to HTTP request splitting attacks, caused
by improper input validation by the path option of an HTTP request. A remote
attacker could exploit this vulnerability to inject arbitrary HTTP request and
cause the browser to send 2 HTTP requests, once the URL is clicked. This would
allow the attacker to perform further attacks, such as Web cache poisoning or
cross-site scripting.
CVSS Base Score: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
153452 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)
CVE-ID: CVE-2018-12123
Description: Node.js is vulnerable to HTTP request splitting attacks, caused
by improper input validation by the path option of an HTTP request. A remote
attacker could exploit this vulnerability to inject arbitrary HTTP request and
cause the browser to send 2 HTTP requests, once the URL is clicked. This would
allow the attacker to perform further attacks, such as Web cache poisoning or
cross-site scripting.
CVSS Base Score: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
153457 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)
CVE-ID: CVE-2018-12120
Description: Node.js could allow a remote attacker to execute arbitrary
JavaScript on the system, caused by a flaw when debugger mode is enabled with
`node --debug` or `node debug`. By sending specially-crafted request to port
5858, an attacker could exploit this vulnerability to execute arbitrary
JavaScript on the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
153454 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVE-ID: CVE-2018-12121
Description: Node.js is vulnerable to a denial of service, caused by improper
validation of HTTP headers. By sending specially-crafted HTTP requests with
maximum sized headers, a remote attacker could exploit this vulnerability to
cause a denial of service condition.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
153455 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVE-ID: CVE-2018-12122
Description: Node.js is vulnerable to a denial of service, caused by improper
validation of HTTP headers. By sending headers very slowly keeping HTTP or
HTTPS connections and associated resources alive for a long period of time, a
remote attacker could exploit this vulnerability to cause a denial of service
condition.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
153456 for more information.
