VMware Workstation 14.1.5 / VMware Player 15 Host VMX Process COM Class Hijack Privilege Escalation

The VMX process vmware-vmx.exe process configures and hosts an instance of VM. As is common with desktop virtualization platforms the VM host usually has privileged access into the OS such as mapping physical memory which represents a security risk. To mitigate this the VMX process is created wit...

CVE-2019-0007

CVE-2019-0007 affects Juniper Networks Junos OS on the vMX Series, with affected releases: 15.1 versions prior to 15.1F5. The root cause is a predictable IP ID sequence number used by the device, enabling a family of attacks that rely on that predictability to compromise the system and clients pa...

Privilege Escalation

Linux kernel is vulnerable to privilege escalation. The VMX code sets the GDT.LIMIT to 64 KB and does not restore it to the previous host value. This allows an attacker is able to escalate their privileges by placing malicious entries to the per-cpu variables in the GDT with a corrupted GDT limit...

Juniper Junos vMX Predictable IP ID Sequence Numbers (JSA10903)

According to its self-reported version number, the remote Junos device uses a predictable IP ID sequence number. It is, therefore, vulnerable to a family of attacks that rely on this property, including a susceptibility to being used as a 'zombie' host in an 'idle scan' blind port scan of another...

RHEL 6 : kernel (RHSA-2018:2391)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2391 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: Modern operating systems implement...

CVE-2018-10901

A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cp...

KVM (Nested Virtualization) - L1 Guest Privilege Escalation Vulnerability

Exploit for linux platform in category dos / poc When KVM on Intel virtualizes another hypervisor as L1 VM it does not verify that VMX instructions from the L1 VM which trigger a VM exit and are emulated by L0 KVM are coming from ring 0. For code running on bare metal or VMX root mode this is...

KVM (Nested Virtualization) - L1 Guest Privilege Escalation

When KVM on Intel virtualizes another hypervisor as L1 VM it does not verify that VMX instructions from the L1 VM which trigger a VM exit and are emulated by L0 KVM are coming from ring 0. For code running on bare metal or VMX root mode this is enforced by hardware. However, for code running in L...
