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

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
