Hash: SHA512
Package : qemu
Version : 1.1.2+dfsg-6+deb7u16
CVE ID : CVE-2016-7161 CVE-2016-7170 CVE-2016-7908
Multiple vulnerabilities have been found in QEMU:
CVE-2016-7161
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.
CVE-2016-7170
The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU (aka Quick
Emulator) is vulnerable to an OOB memory access.
CVE-2016-7908
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.
