Critical Nessus Plugin ID 87705


The remote FreeBSD host is missing one or more security-related updates.


Prasad J Pandit, Red Hat Product Security Team, reports :

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.
