QEMU: i386: multiboot OOB access while loading kernel image

Quick Emulator QEMU, compiled with the PC System Emulator with multiboot feature support, is vulnerable to an OOB r/w memory access issue. The issue could occur while loading a kernel image during the guest boot, if mhloadendaddr address is greater than the mhbssendaddr address. A user or process...

UBUNTU-CVE-2018-7550

The loadmultiboot function in hw/i386/multiboot.c in Quick Emulator aka QEMU allows local guest OS users to execute arbitrary code on the QEMU host via a mhloadendaddr value greater than mhbssendaddr, which triggers an out-of-bounds read or write memory access...

CVE-2017-4950

VMware Workstation and Fusion contain an integer overflow vulnerability in VMware NAT service when IPv6 mode is enabled. This issue may lead to an out-of-bound read which can then be used to execute code on the host in conjunction with other issues. Note: IPv6 mode for VMNAT is not enabled by...

VMware Workstation and Fusion Heap Buffer Overflow Vulnerability

VMWare Workstation and Fusion are both desktop virtual computer software from VMware. The former provides virtual machine functionality that allows you to run several different operating systems at the same time, while the latter is virtual machine software used to run Windows applications on App...

CVE-2017-4934

VMware Workstation 12.x before 12.5.8 and Fusion 8.x before 8.5.9 contain a heap buffer-overflow vulnerability in VMNAT device. This issue may allow a guest to execute code on the host...

The vulnerability of the load_multiboot function (hw/i386/multiboot.c) in the QEMU hardware emulation driver allows a hacker to execute arbitrary code.

The vulnerability of the loadmultiboot function hw/i386/multiboot.c in the QEMU hardware emulation driver is caused by a numerical overflow. Exploiting this vulnerability allows a attacker operating on the local guest operating system to execute arbitrary code on the host operating system using a...

UBUNTU-CVE-2017-15588

An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to execute arbitrary code on the host OS because of a race condition that can cause a stale TLB entry...
