CVE-2018-12547

The CVE-2018-12547 issue affects Eclipse OpenJ9 where jio_snprintf() and jio_vsnprintf() fail to honor the input length, allowing buffer overflow. IBM advisories corroborate this vulnerability (CVE-2018-12547) within IBM Java SDK/JVM ecosystems and list affected IBM products (SAN Volume Controlle...

CVE-2021-41035

CVE-2021-41035 affects Eclipse OpenJ9 prior to 0.29.0. The root cause is that the JVM does not throw IllegalAccessError for MethodHandles invoking inaccessible interface methods. This could allow a remote attacker to gain elevated privileges and execute arbitrary code on the system; exploitation ...

CVE-2018-12539

CVE-2018-12539 affects IBM/OpenJ9-based JVMs where the Java Attach API can be used by non-owners to connect to a local OpenJ9/IBM JVM and run untrusted native code. By default Attach API is enabled on Windows, Linux and AIX; a workaround is to disable it with -Dcom.ibm.tools.attach.enable=no. IBM...

CVE-2019-11772

CVE-2019-11772 affects OpenJ9 (prior to 0.15). The vulnerability is an out-of-bounds write in String.getBytes invoked by JIT, allowing a local attacker to write memory at arbitrary 32-bit addresses or beyond the end of a byte array when Java runs under a SecurityManager. IBM/IBM X-Force entries t...

CVE-2024-3933

CVE-2024-3933 affects IBM OpenJ9/OpenJDK builds older than 0.44.0 (and between 0.13.0) on IBM Z with guarded storage, where arraycopy during Concurrent Scavenge GC can permit reading/writing beyond the end of the source/destination, due to a mismatch in System.arrayCopy length handling. The vulne...

CVE-2018-12549

CVE-2018-12549 affects Eclipse OpenJ9 VM up to version 0.11.0, where the JIT compiler may omit a null check on the receiver object of an Unsafe call during acceleration.
