Security Bulletin: Vulnerabilities in Java SE and Eclipse OpenJ9 affect IBM Control Center (CVE-2020-14803 & CVE-2020-27221)

Security Bulletin


Summary

A buffer overflow flaw has been found in a widely used function in the OpenJ9 JVM, which is employed when writingcharacters to a file. We have not identified any specific exploits, but it is very likely that the flaw is exploitable to trigger a crash or run arbitrary code. The fix ensures that the buffer cannot overflow.

Vulnerability Details

CVEID:   CVE-2020-14803
DESCRIPTION:   An unspecified vulnerability in Java SE could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/190121 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:   CVE-2020-27221
DESCRIPTION:   Eclipse OpenJ9 is vulnerable to a stack-based buffer overflow when the virtual machine or JNI natives are converting from UTF-8 characters to platform encoding. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/195353 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
