Call vbe_update_vgaregs() when the guest touches GFX, SEQ or CRT registers, to make sure the vga registers will always have the values needed by vbe mode. This makes sure the sanity checks applied by vbe_fixup_regs() are effective. Without this guests can muck with shift_control, can turn on planar vga modes or text mode emulation while VBE is active, making qemu take code paths meant for CGA compatibility, but with the very large display widths and heigts settable using VBE registers. Which is good for one or another buffer overflow. Not that critical as they typically read overflows happening somewhere in the display code. So guests can DoS by crashing qemu with a segfault, but it is probably not possible to break out of the VM. upstream-commit-id: fd3c136b3e1482cd0ec7285d6bc2a3e6a62c38d7 Fixes: CVE-2016-3712 Reported-by: Zuozhi Fzz <zuozhi.fzz@xxxxxxxxxxxxxxx> Reported-by: P J P <ppandit@xxxxxxxxxx> Signed-off-by: Gerd Hoffmann <kraxel@xxxxxxxxxx> Signed-off-by: Stefano Stabellini <sstabellini@xxxxxxxxxx> commit 5ee8a0795e9656b370e9f67b6acea2f2690a1aca Author: Gerd Hoffmann <kraxel@xxxxxxxxxx> Date: Wed May 4 17:42:59 2016 +0100 vga: update vga register setup on vbe changes Call the new vbe_update_vgaregs() function on vbe configuration changes, to make sure vga registers are up-to-date. upstream-commit-id: 2068192dcccd8a80dddfcc8df6164cf9c26e0fc4 Signed-off-by: Gerd Hoffmann <kraxel@xxxxxxxxxx> Signed-off-by: Stefano Stabellini <sstabellini@xxxxxxxxxx> commit 7073ff0127babd7d8b35326cf50753b337b23bb0 Author: Gerd Hoffmann <kraxel@xxxxxxxxxx> Date: Wed May 4 17:42:24 2016 +0100 vga: factor out vga register setup When enabling vbe mode qemu will setup a bunch of vga registers to make sure the vga emulation operates in correct mode for a linear framebuffer.

The VBE bochs extentions support banked access too, using the VBE_DISPI_INDEX_BANK register. The code tries to take the different address calculations into account and applies different limits to VBE_DISPI_INDEX_BANK depending on the current access mode. Which is probably effective in stopping misprogramming by accident. But from a security point of view completely useless as an attacker can easily change access modes after setting the bank register. Drop the bogus check, add range checks to vga_mem_{readb,writeb} instead. upstream-commit-id: 3bf1817079bb0d80c0d8a86a7c7dd0bfe90eb82e Fixes: CVE-2016-3710 Reported-by: Qinghao Tang <luodalongde@xxxxxxxxx> Signed-off-by: Gerd Hoffmann <kraxel@xxxxxxxxxx> Signed-off-by: Stefano Stabellini <sstabellini@xxxxxxxxxx> _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
