VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host.
Se ha descubierto que la implementación del servidor VNC en Quick Emulator (QEMU) 2.11.0 y anteriores es vulnerable a un problema de asignación de memoria sin enlazar, ya que no limitó las actualizaciones de framebuffer enviadas a su cliente. Si el cliente no consume estas actualizaciones, el servidor de VNC asigna memoria que va creciendo para albergar estos datos. Un cliente VCN malicioso remoto podría emplear este fallo para provocar DoS en el host del servidor.
