Description Tomas Hoger 2019-03-05 21:36:26 UTC
IBM JDK 8 SR5 FP30 (8.0.5.30) fixes a flaw described by upstream as:

Eclipse OpenJ9 could allow a remote attacker to execute arbitrary code on the system, caused by the failure to omit a null check on the receiver object of an Unsafe call when accelerating it. An attacker could exploit this vulnerability to execute arbitrary code on the system.

Statement:

This issue affects the versions of the  java-1.8.0-ibm package as shipped with Red Hat Satellite 5. However, OpenJ9 is loaded only by taskomatic and Tomcat. These 2 processes are listening on the loopback interface only. This flaw is not known to be remotely exploitable under any supported scenario in Satellite 5.
