Al escribir una cabecera QCOW maliciosa en un disco raíz o efímero y luego activar un redimensionamiento, un usuario puede inducir al backend de imagen Flat de Nova a llamar a qemu-img sin una restricción de formato, lo que resulta en una operación de redimensionamiento de imagen insegura que podría destruir datos en el sistema anfitrión.

By writing a malicious QCOW header to a root or ephemeral disk and then triggering a resize, a user may convince Nova's Flat image backend to call qemu-img without a format restriction, resulting in an unsafe image resize operation that could destroy data on the host system. Only compute nodes using the Flat image backend (usually configured with use_cow_images=False) are affected."

Al escribir una cabecera QCOW maliciosa en un disco raíz o efímero y luego activar un redimensionamiento, un usuario puede inducir al backend de imagen Flat de Nova a llamar a qemu-img sin una restricción de formato, lo que resulta en una operación de redimensionamiento de imagen insegura que podría destruir datos en el sistema anfitrión.

Al escribir una cabecera QCOW maliciosa en un disco raíz o efímero y luego activar un redimensionamiento, un usuario puede inducir al backend de imagen Flat de Nova a llamar a qemu-img sin una restricción de formato, lo que resulta en una operación de redimensionamiento de imagen insegura que podría destruir datos en el sistema anfitrión.

| An issue was discovered in OpenStack Nova before 30.2.2, 31 before 31.2.1, and 32 before 32.1.1. By writing a malicious QCOW header to a root or ephemeral disk and then triggering a resize, a user may convince Nova's Flat image backend to call qemu-img without a format restriction, resulting in an unsafe image resize operation that could destroy data on the host system. Only compute nodes using the Flat image backend (usually configured with use_cow_images=False) are affected. zetlyn/cve-nvd · 2026-02-18 | cvss 8.2 product Nova status Deferred vendor OpenStack | source |
