Description Prasad Pandit 2017-11-16 17:57:02 UTC
Quick Emulator(Qemu) built with the PS/2 keyboard and mouse emulation
support along with the migration feature enabled is vulnerable to an
information leakage flaw. It could occur while loading a migrated
snapshot on the destination host in PS2 post_load routine.

A privileged user could use this flaw to leak destination host memory
