ALPINE-CVE-2020-29481
An issue was discovered in Xen through 4.14.x. Access rights of Xenstore nodes are per domid. Unfortunately, existing granted access rights are not removed when a domain is being destroyed. This means that a new domain created with the same domid will inherit the access rights to Xenstore nodes...
DEBIAN-CVE-2020-29486
An issue was discovered in Xen through 4.14.x. Nodes in xenstore have an ownership. In oxenstored, a owner could give a node away. However, node ownership has quota implications. Any guest can run another guest out of quota, or create an unbounded number of nodes owned by dom0, thus running...
DEBIAN-CVE-2020-29567
An issue was discovered in Xen 4.14.x. When moving IRQs between CPUs to distribute the load of IRQ handling, IRQ vectors are dynamically allocated and de-allocated on the relevant CPUs. De-allocation has to happen when certain constraints are met. If these conditions are not met when first checke...
CVE-2020-29566
An issue was discovered in Xen through 4.14.x. When they require assistance from the device model, x86 HVM guests must be temporarily de-scheduled. The device model will signal Xen when it has completed its operation, via an event channel, so that the relevant vCPU is rescheduled. If the device...
CVE-2020-27777
The CVE-2020-27777 issue concerns the Linux kernel on PowerPC: RTAS memory accesses in the userspace-to-kernel path allow a local, root-like user on a locked-down guest (Secure Boot) running on PowerVM or KVM/pseries to escalate privileges to the running kernel. Root cause is an improper handling...
