UBUNTU-CVE-2016-9603

A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this fla...

Design/Logic Flaw

QEMU aka Quick Emulator built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit tx descriptors in 'txconsume' routine, if a descriptor was to have more than allowed ROCKERTXFRAGSMAX=16 fragments. A privileged user inside guest coul...
