Descriptions

A flaw was found in RPC request using gfs3_symlink_req in glusterfs server which allows symlink destinations to point to file paths outside of the gluster volume. An authenticated attacker could use this flaw to create arbitrary symlinks pointing anywhere on the server and execute arbitrary code on glusterfs server nodes.

Se ha detectado un error en las peticiones RPC que emplean gfs3_symlink_req en el servidor glusterfs, lo que permite que los destinos symlink señalen a rutas de archivo fuera del volumen gluster. Un atacante autenticado podría emplear este error para crear symlinks arbitrarios que señalen a cualquier lugar del servidor y ejecutar código arbitrario en un nodo del servidor glusterfs.
