CVE-2020-35510 – jboss-remoting: Threads hold up forever in the EJB server by suppressing the ack from an EJB client
https://notcve.org/view.php?id=CVE-2020-35510
A flaw was found in jboss-remoting in versions before 5.0.20.SP1-redhat-00001. A malicious attacker could cause threads to hold up forever in the EJB server by writing a sequence of bytes corresponding to the expected messages of a successful EJB client request, but omitting the ACK messages, or just tamper with jboss-remoting code, deleting the lines that send the ACK message from the EJB client code resulting in a denial of service. The highest threat from this vulnerability is to system availability. Se ha encontrado un fallo en jboss-remoting en versiones anteriores a 5.0.20.SP1-redhat-00001. Un atacante malicioso podría causar que los hilos (subprocesos) se quedaran detenidos para siempre en el servidor EJB al escribir una secuencia de bytes correspondientes a los mensajes esperados de una petición de cliente EJB con éxito, pero omitiendo los mensajes ACK, o simplemente manipulando el código de jboss-remoting, borrando las líneas que envían el mensaje ACK del código del cliente EJB, resultando en una Denegación de Servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=1905796 https://access.redhat.com/security/cve/CVE-2020-35510 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2019-19343
A flaw was found in Undertow when using Remoting as shipped in Red Hat Jboss EAP before version 7.2.4. A memory leak in HttpOpenListener due to holding remote connections indefinitely may lead to denial of service. Versions before undertow 2.0.25.SP1 and jboss-remoting 5.0.14.SP1 are believed to be vulnerable.

CVE-2018-1041 – JBoss Remoting 6.14.18 - Denial of Service
https://notcve.org/view.php?id=CVE-2018-1041
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. Se ha encontrado una vulnerabilidad en la forma en la que RemoteMessageChannel, introducido en las versiones 3.3.10 de jboss-remoting, lee desde un búfer vacío. Un atacante podría emplear este error para provocar una denegación de servicio (DoS) mediante un consumo alto de CPU a través de un bucle infinito. A vulnerability was found in the way RemoteMessageChannel, introduced in jboss-remoting versions 3.3.10.Final-redhat-1, reads from an empty buffer. • https://www.exploit-db.com/exploits/44099 http://www.securitytracker.com/id/1040323 https://access.redhat.com/errata/RHSA-2018:0268 https://access.redhat.com/errata/RHSA-2018:0269 https://access.redhat.com/errata/RHSA-2018:0270 https://access.redhat.com/errata/RHSA-2018:0271 https://access.redhat.com/errata/RHSA-2018:0275 https://bugzilla.redhat.com/show_bug.cgi?id=1530457 https://access.redhat.com/security/cve/CVE-2018-1041 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
