IBM PureApplication System is vulnerable to Venom: "Virtualized Environment Neglected Operation Manipulation".
DESCRIPTION: QEMU is vulnerable to a buffer overflow, caused by improper bounds checking by the Floppy Disk Controller (FDC) emulation. By sending specially crafted FDC commands, a guest operating system attacker with access to the FDC I/O ports could overflow a buffer and execute arbitrary code on the system with root privileges. Note: This vulnerability is also being called VENOM.
