Descriptions

Jenkins Subversion Plugin 2.15.0 and earlier does not restrict the name of a file when looking up a subversion key file on the controller from an agent.

Jenkins Subversion Plugin versiones 2.15.0 y anteriores, no restringe el nombre de un archivo cuando es buscado un archivo de claves de subversión en el controlador desde un agente

An incorrect access restriction vulnerability was found in the Subversion Plugin for Jenkins. An agent's ability to learn the name of a file is not restricted when looking up a subversion key file on the controller. This may allow attackers to control agent processes and read arbitrary files on the Jenkins controller file system.

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the RPM packages for Red Hat OpenShift Container Platform 4.8.22. Issues addressed include a bypass vulnerability.
