CVE-2020-2654: Low severity IBM Security Identity Manager Virtual Appliance vulnerability

Published Jan 14, 2020
·
Updated

A flaw was discovered in the way the Libraries component of OpenJDK processed X.509 certificates. Values of Object Identifiers (OIDs) were "interned", possibly allowing a malicious X.509 certificate to trigger excessive memory usage in a Java application processing such certificate.

Other sources

An unspecified vulnerability in Java SE related to the Java SE Libraries component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.

— IBM

Vulnerability in the Java SE product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 7u241, 8u231, 11.0.5 and 13.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE. Note: This vulnerability can only be exploited by supplying data to APIs in the specified Component without using Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. CVSS 3.0 Base Score 3.7 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
