Description Tomas Hoger 2019-03-05 16:18:18 UTC

IBM JDK 8 SR5 FP30 (8.0.5.30) and IBM JDK 7R1 SR4 FP40 (7.1.4.40) fix a flaw described by upstream as:

Eclipse OpenJ9 is vulnerable to a buffer overflow, caused by improper bounds checking by the jio_snprintf() and jio_vsnprintf() functions. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

OpenJ9 upstream bug and commit:

Comment 5 Cedric Buissart 2019-03-18 13:18:37 UTC

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.
