Descriptions

Multiple directory traversal vulnerabilities in OpenStack Nova before 2011.3.1, when the EC2 API and the S3/RegisterImage image-registration method are enabled, allow remote authenticated users to overwrite arbitrary files via a crafted (1) tarball or (2) manifest.

Múltiples vulnerabilidades de salto de directorio en OpenStack Nova anterior a v2011.3.1, cuando el EC2 API y el método S3/RegisterImage image-registration están habilitados, cuando está habilitado register_globals, permite que usuarios remotos autenticados sobrescriban archivos arbitrarios a través de una (1) tarball o (2) manifest manipulado.
