CVE-2019-3804

Se ha detectado que cockpit, en versiones anteriores a la 184, empleaba incorrectamente la funcionalidad de descodificación de base64 de glib, lo que resultaba en un ataque de denegación de servicio (DoS). Un atacante no autenticado podría enviar una petición especialmente manipulada con una cookie no válida codificada en base64, lo que podría provocar el cierre inesperado del servicio web.

It was found that cockpit used glib's base64 decode functionality incorrectly resulting in a denial of service attack. An unauthenticated attacker could send a specially crafted request with an invalid base64-encoded cookie which could cause the web service to crash.

The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. A crash issue when parsing invalid base64 headers was addressed.
