SynopsisThe remote Debian host is missing a security update.
DescriptionMultiple vulnerabilities have been found in qemu-kvm :
Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite in qemu-kvm 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-kvm is vulnerable to an OOB memory access.
The mcf_fec_do_tx function in hw/net/mcf_fec.c in qemu-kvm 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-kvm packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected kvm, qemu-kvm, and qemu-kvm-dbg packages.
