QEMU 'pit_ioport_read()' function memory corruption vulnerability

QEMU is an open source emulator software. QEMU has a memory corruption vulnerability in the pitioportread function, which allows an attacker to exploit this vulnerability to execute arbitrary code on the host...

UBUNTU-CVE-2015-3214

The pitioportread in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index...

Xen QEMU PCNET Controller Heap Overflow Vulnerability

Xen is a virtualization technology for the Linux kernel that allows multiple operating systems to run simultaneously. A heap overflow vulnerability exists in the Xen QEMU PCNET device controller, which allows an attacker to execute arbitrary code on the host in the context of a QEMU process...

qemu: pcnet: multi-tmd buffer overflow in the tx path

A flaw was found in the way QEMU's AMD PCnet Ethernet emulation handled multi-TMD packets with a length above 4096 bytes. A privileged guest user in a guest with an AMD PCNet ethernet card enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the...
