Red Hat Security Advisory: java-1.8.0-ibm security update

Critical

Buffer overflow in the Java Virtual Machine (JVM) in IBM SDK, Java Technology Edition 6 before SR16 FP25 (6.0.16.25), 6 R1 before SR8 FP25 (6.1.8.25), 7 before SR9 FP40 (7.0.9.40), 7 R1 before SR3 FP40 (7.1.3.40), and 8 before SR3 (8.0.3.0) allows remote attackers to execute arbitrary code via unspecified vectors.

CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The com.ibm.CORBA.iiop.ClientDelegate class in IBM SDK, Java Technology Edition 6 before SR16 FP25 (6.0.16.25), 6 R1 before SR8 FP25 (6.1.8.25), 7 before SR9 FP40 (7.0.9.40), 7 R1 before SR3 FP40 (7.1.3.40), and 8 before SR3 (8.0.3.0) uses the invoke method of the java.lang.reflect.Method class in an AccessController doPrivileged block, which allows remote attackers to call setSecurityManager and bypass a sandbox protection mechanism via vectors related to a Proxy object instance implementing the java.lang.reflect.InvocationHandler interface. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-3009.

The com.ibm.rmi.io.SunSerializableFactory class in IBM SDK, Java Technology Edition 6 before SR16 FP25 (6.0.16.25), 6 R1 before SR8 FP25 (6.1.8.25), 7 before SR9 FP40 (7.0.9.40), 7 R1 before SR3 FP40 (7.1.3.40), and 8 before SR3 (8.0.3.0) does not properly deserialize classes in an AccessController doPrivileged block, which allows remote attackers to bypass a sandbox protection mechanism and execute arbitrary code as demonstrated by the readValue method of the com.ibm.rmi.io.ValueHandlerPool.ValueHandlerSingleton class, which implements the javax.rmi.CORBA.ValueHandler interface. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-5456.

Unspecified vulnerability in Oracle Java SE 6u113, 7u99, and 8u77 and Java SE Embedded 8u77 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to Serialization.

Unspecified vulnerability in Oracle Java SE 6u113, 7u99, and 8u77 and Java SE Embedded 8u77 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to the Hotspot sub-component.

Unspecified vulnerability in Oracle Java SE 6u113, 7u99, and 8u77 allows remote attackers to affect availability via vectors related to 2D.

It was discovered that the GCM (Galois/Counter Mode) implementation in the JCE component in OpenJDK used a non-constant time comparison when comparing GCM authentication tags. A remote attacker could possibly use this flaw to determine the value of the authentication tag.

It was discovered that the RMI server implementation in the JMX component in OpenJDK did not restrict which classes can be deserialized when deserializing authentication credentials. A remote, unauthenticated attacker able to connect to a JMX port could possibly use this flaw to trigger deserialization flaws.

Unspecified vulnerability in Oracle Java SE 6u113, 7u99, and 8u77 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to 2D. NOTE: the previous information is from the April 2016 CPU. Oracle has not commented on third-party claims that this issue allows remote attackers to obtain sensitive information via crafted font data, which triggers an out-of-bounds read.
