CVE-2019-19579

CVE-2019-19579 affects the Xen hypervisor up to 4.12.x. It arises when an untrusted domain has access to a PCI device and the incomplete fix for CVE-2019-18424 leaves the system vulnerable if alternate PCI assignment methods are used (libxl assignable-add not strictly required). The issue enables...

CVE-2019-19579

An issue was discovered in Xen through 4.12.x allowing attackers to gain host OS privileges via DMA in a situation where an untrusted domain has access to a physical device and assignable-add is not used, because of an incomplete fix for CVE-2019-18424. XSA-302 relies on the use of libxl's...

CVE-2019-18424

An issue was discovered in Xen through 4.12.x allowing attackers to gain host OS privileges via DMA in a situation where an untrusted domain has access to a physical device. This occurs because passed through PCI devices may corrupt host memory after deassignment. When a PCI device is assigned to...

CVE-2019-18421

An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations. There are issues with restartable PV type change operations. To avoid using shadow pagetables for PV guests, Xen...

CVE-2019-18421

CVE-2019-18421 affects the Xen hypervisor on x86 PV guests. Root cause: restartable PV type changes with recursive pagetable promotions/demotions contain races that can lead to incorrect type counts, enabling a PV guest to gain host privileges. Impact: local privilege escalation to host OS on all...

VMware Workstation e1000 Out-Of-Bounds Write Privilege Escalation Vulnerability

This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of VMware Workstation. An attacker must first obtain the ability to execute low-privileged code on the guest system in order to exploit this vulnerability. The specific flaw exists within the handling ...

The ThreadX-based firmware on Marvell Avastar Wi-Fi devices, models 88W8787, 88W8797, 88W8801, 88W8897, and 88W8997, allows remote attackers to execute arbitrary code or cause a denial of service block pool overflow via malformed Wi-Fi packets during identification of available Wi-Fi networks...

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...
