It was discovered that the jboss init script performed unsafe file handling which could result in local privilege escalation.
A vulnerability which allows for a potential privilege escalation was found in the Hibernate Validator. If a security manager is present and HV itself is allowed to access private members reflectively as per the SM's configuration, that'll allow calling code without that permission to get hold of private state. The attack vector is to declare a constraint on a private member using XML, validate an invalid instance of that type and access the private member value via ConstraintViolation#getInvalidValue().
dom4j could allow a remote attacker to execute arbitrary code on the system, caused by improper input validation in multiple methods. By sending a specially-crafted XML content, an attacker could exploit this vulnerability to execute arbitrary code on the system.
An improper handing of overflow in the UTF-8 decoder with supplementary characters can lead to an infinite loop in the decoder causing a Denial of Service. Versions Affected: Apache Tomcat 9.0.0.M9 to 9.0.7, 8.5.0 to 8.5.30, 8.0.0.RC1 to 8.0.51, and 7.0.28 to 7.0.86.
A vulnerability was found in the way RemoteMessageChannel, introduced in jboss-remoting versions 3.3.10, reads from an empty buffer. An attacker could use this flaw to cause denial of service via high CPU caused by an infinite loop.
A class implementing the Serializable interface is free to implement the “readObject(java.io.ObjectInputStream in)” method however it chooses. This readObject method is used during the deserialization process, when constructing a java object from a serialized byte stream. It is possible to implement the method in such a way that can result in java code being executed during the deserialization of an object of this class (gadget class).
The JMS specification outlines a getObject() method on the javax.jms.ObjectMessage class. The Apache Artemis implementation of this method allows deserialization of objects, from untrusted input. There are several places where Apache Artemis uses this getObject() method. In the JMS Core client, the Artemis broker and the Artemis REST component. These Artemis components may therefore be vulnerable to a remote code execution attack. Successful exploitations of this vulnerability rely on these "gadget classes" being present on the Artemis classpath and the sender of the untrusted input being authenticated and authorized to send messages to the Artemis broker.
An issue was found in the Artemis and HornetQ .When 3rd party tool send multicast messages to Artemis/HornetQ which is configured with UDP Disovery and JGroups Discovery, Artemis/HornetQ creates a huge byte array at receiving the unexpected multicast message. So, it results in heap memory exhaustion, full GC and OutOfMemoryError in the worst case.
A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients.
