SynopsisThe remote Debian host is missing a security update.
DescriptionMultiple vulnerabilities have been found in QEMU :
Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite in QEMU (aka Quick Emulator) allows attackers to execute arbitrary code on the QEMU host via a large ethlite packet.
The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU (aka Quick Emulator) is vulnerable to an OOB memory access.
The mcf_fec_do_tx function in hw/net/mcf_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags.
For Debian 7 'Wheezy', these problems have been fixed in version 1.1.2+dfsg-6+deb7u16.
We recommend that you upgrade your qemu packages.
