CVE-2019-3812 qemu: Out-of-bounds read in hw/i2c/i2c-ddc.c allows for memory disclosure
QEMU through version 2.10 through to 3.1.0 is vulnerable to an out-of-bounds read
of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker
with permission to execute i2c commands could exploit this to read stack memory
of the qemu process on the host.
Systems without a monitor connected are affected, a virtual monitor is presented
to virtual guests. Systems with no graphics cards attached to the virtual host
are not affected.
