From ${URL} : Qemu emulator built with the IDE disk and CD/DVD-ROM emulation support is vulnerable to a divide by zero issue. It could occur while executing an IDE command WIN_READ_NATIVE_MAX to determine the maximum size of a drive. A privileged user inside guest could use this flaw to crash the Qemu instance resulting in DoS. Upstream fix: ------------- -> https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg02479.html The fix disables undue IDE commands for CD-ROM drives. @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

qemu-2.4.0.1 in the tree should have the fixes for this and should be fine to mark stable http://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4703b062bb7d0c6ebdf91827a3396435e6dea74a
