The vulnerability of the USB 2.0 controller EHCI in VMware ESXi, VMware Workstation, and VMware Fusion stems from synchronization errors when using shared resources „Race Conditions“. Exploiting this vulnerability allows an attacker to execute arbitrary code...
Nexus 9000 Series Switches Standalone NX-OS Mode Fibre Channel over Ethernet NPV DoS Vulnerability (cisco-sa-20190306-nxos-npv-dos)
According to its self-reported version, Cisco NX-OS Software is affected by a denial of service DoS vulnerability exists in Fibre Channel over Ethernet N-port Virtualization due to incorrect processing of FCoE packets. An unauthenticated, adjacent attacker can exploit this issue, via sending a...
Introducing Kernel Data Protection, a new platform security technology for preventing data corruption
Attackers, confronted by security technologies that prevent memory corruption, like Code Integrity CI and Control Flow Guard CFG, are expectedly shifting their techniques towards data corruption. Attackers use data corruption techniques to target system security policy, escalate privileges, tampe...
Configuring a Windows Domain to Dynamically Analyze an Obfuscated Lateral Movement Tool
We recently encountered a large obfuscated malware sample that offered several interesting analysis challenges. It used virtualization that prevented us from producing a fully-deobfuscated memory dump for static analysis. Statically analyzing a large virtualized sample can take anywhere from...
Kernel: ppc: kvm: conflicting use of HSTATE_HOST_R1 to store r1 state leads to host stack corruption
A flaw was found in the way the KVM hypervisor on the Power8 processor stores the r1 register state in the 'HSTATEHOSTR1' field on the Linux kernel stack. This flaw occurs while handling hypercalls in Transactional Memory TM suspend mode in the kvmppcsavetm and kvmppcrestoretm routines, leading t...
Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario
A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable access to the devices' MMIO memory address spaces. If a user attempts to access the...
DEBIAN-CVE-2020-15567
An issue was discovered in Xen through 4.13.x, allowing Intel guest OS users to gain privileges or cause a denial of service because of non-atomic modification of a live EPT PTE. When mapping guest EPT nested paging tables, Xen would in some circumstances use a series of non-atomic bitfield write...
DEBIAN-CVE-2020-15563
An issue was discovered in Xen through 4.13.x, allowing x86 HVM guest OS users to cause a hypervisor crash. An inverted conditional in x86 HVM guests' dirty video RAM tracking code allows such guests to make Xen de-reference a pointer guaranteed to point at unmapped space. A malicious or buggy HV...
