Descriptions
qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.
qmp_guest_file_read en qga/commands-posix.c y qga/commands-win32.c en qemu-ga (también conocido como QEMU Guest Agent) en QEMU 2.12.50 tiene un desbordamiento de enteros que provoca que una llamada g_malloc0() desencadene un fallo de segmentación al intentar asignar un gran fragmento de memoria. La vulnerabilidad puede ser explotada mediante el envío de un comando QMP manipulado (incluyendo guest-file-read con un valor largo de conteo) al agente mediante el socket en escucha.
QEMU Guest Agent version 2.12.50 suffers from a denial of service vulnerability.
