Description Victor Pereira 2015-09-11 07:19:01 UTC

rh#1260080

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.
