There are multiple vulnerabilities in IBM® SDKs Java™ Technology Edition, Versions 7 and 8, as used by IBM Virtualization Engine TS7700. These issues were disclosed as part of the IBM Java SDK updates in October 2020 and January 2021. IBM Virtualization Engine TS7700 has addressed the applicable CVEs.
CVEID:CVE-2020-14782
**DESCRIPTION:**An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause no confidentiality impact, low integrity impact, and no availability impact.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/190100 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/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)
CVEID:CVE-2020-14781
**DESCRIPTION:**An unspecified vulnerability in Java SE related to the JNDI component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors.
CVSS Base score: 3.7
