Description Martin Prpič 2016-04-28 09:10:21 EDT
Qemu emulator built with VGA emulation with VESA BIOS Extensions(VBE) support is vulnerable to an OOB r/w access issue. It could occur while doing VGA r/w operations via i/o port methods.

A privileged guest user could use this flaw to potentially execute arbitrary code, with privileges of the Qemu process on the host.
