Description Prasad Pandit 2014-05-13 12:09:09 UTC

Qemu block driver for the QCOW version 1 image format is vulnerable to an
integer overflow flaw. It occurs due to weak input validations or logic errors.
Such integer overflow could lead to buffer overflows, memory corruption or
crash in Qemu instance.

An user able to alter the Qemu disk image files loaded by a guest could use
this flaw to crash the Qemu instance resulting in DoS or corrupt QEMU process
memory on the host, which could potentially result in arbitrary code execution
on the host with the privileges of the QEMU process.
