Arbitrary Code Execution

qemu-kvm-rhev is vulnerable to arbitrary code execution attacks. The vulnerability exists as 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...

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...

CVE-2015-3214

CVE-2015-3214 affects QEMU prior to 2.3.1 (pit_ioport_read in i8254.c) and Linux kernel prior to 2.6.33. The flaw does not distinguish between read and write lengths, potentially allowing a privileged guest user (with PIT emulation enabled) to trigger an invalid index and cause arbitrary host cod...

CVE-2011-4622

CVE-2011-4622 affects KVM (arch/x86/kvm/i8254.c) where create_pit_timer mishandles PIT IRQs if an irqchip is not available, allowing a local user to trigger a denial-of-service via NULL pointer dereference by starting a PIT timer. The vulnerability is referenced in MiracleLinux AXSA advisories as...

Design/Logic Flaw

The pitioportread function in the Programmable Interval Timer PIT emulation in i8254.c in KVM 83 does not properly use the pitstate data structure, which allows guest OS users to cause a denial of service host OS crash or hang by attempting to read the /dev/port file...
