Eclipse Openj9: vulnerabilidades y CVE

In Eclipse OpenJ9 versions up to 0.60, when executing class files where a previously concrete superclass method has been recompiled as abstract, execution is incorrectly delegated to an interface default method.

In Eclipse OpenJ9 versions up to 0.60, using -Xtrace to trace method arguments can lead to buffer underflow.

In Eclipse Open9J versions 0.21 to 0.58, a pre-authentication remote attacker can crash JITServer by sending a 32-byte crafted TCP message.

In Eclipse OpenJ9 versions up to 0.51, when used with OpenJDK version 8 a stack based buffer overflow can be caused by modifying a file on disk that is read when the JVM starts.

In Eclipse OpenJ9 versions up to 0.47, the JNI function GetStringUTFLength may return an incorrect value which has wrapped around. From 0.48 the value is correct but may be truncated to include a smaller number of…

In Eclipse OpenJ9 release versions prior to 0.44.0 and after 0.13.0, when running with JVM option -Xgc:concurrentScavenge, the sequence generated for System.arrayCopy on the IBM Z platform with hardware and software…

In Eclipse OpenJ9 before version 0.41.0, the JVM can be forced into an infinite busy hang on a spinlock or a segmentation fault if a shutdown signal (SIGTERM, SIGINT or SIGHUP) is received before the JVM has finished…

In Eclipse Openj9 before version 0.38.0, in the implementation of the shared cache (which is enabled by default in OpenJ9 builds) the size of a string is not properly checked against the size of the buffer.

In Eclipse Openj9 before version 0.35.0, interface calls can be inlined without a runtime type check. Malicious bytecode could make use of this inlining to access or modify memory via an incompatible type.

In Eclipse Openj9 before version 0.32.0, Java 8 & 11 fail to throw the exception captured during bytecode verification when verification is triggered by a MethodHandle invocation, allowing unverified methods to be…

In Eclipse Openj9 before version 0.29.0, the JVM does not throw IllegalAccessError for MethodHandles that invoke inaccessible interface methods.

In Eclipse Openj9 to version 0.25.0, usage of the jdk.internal.reflect.ConstantPool API causes the JVM in some cases to pre-resolve certain constant pool entries. This allows a user to call static methods or access…

In Eclipse OpenJ9 up to and including version 0.23, there is potential for a stack-based buffer overflow when the virtual machine or JNI natives are converting from UTF-8 characters to platform encoding.

In Eclipse OpenJ9 prior to version 0.21 on Power platforms, calling the System.arraycopy method with a length longer than the length of the source or destination array can, in certain specially crafted code patterns,…

From Eclipse OpenJ9 0.15 to 0.16, access to diagnostic operations such as causing a GC or creating a diagnostic file are permitted without any privilege checks.

All builds of Eclipse OpenJ9 prior to 0.15 contain a bug where the loop versioner may fail to privatize a value that is pulled out of the loop by versioning - for example if there is a condition that is moved out of the…

In Eclipse OpenJ9 prior to 0.15, the String.getBytes(int, int, byte[], int) method does not verify that the provided byte array is non-null nor that the provided index is in bounds when compiled by the JIT. This allows…

AIX builds of Eclipse OpenJ9 before 0.15.0 contain unused RPATHs which may facilitate code injection and privilege elevation by local users.

In Eclipse OpenJ9 prior to the 0.14.0 release, the Java bytecode verifier incorrectly allows a method to execute past the end of bytecode array causing crashes. Eclipse OpenJ9 v0.14.0 correctly detects this case and…

In Eclipse OpenJ9 version 0.11.0, the OpenJ9 JIT compiler may incorrectly omit a null check on the receiver object of an Unsafe call when accelerating it.

In Eclipse OpenJ9, prior to the 0.12.0 release, the jio_snprintf() and jio_vsnprintf() native methods ignored the length parameter. This affects existing APIs that called the functions to exceed the allocated buffer.…

In OpenJDK + Eclipse OpenJ9 version 0.11.0 builds, the public jdk.crypto.jniprovider.NativeCrypto class contains public static natives which accept pointer values that are dereferenced in the native code.

In Eclipse OpenJ9 version 0.8, users other than the process owner may be able to use Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations, which includes the…
