Debian DSA-4566-1 : qemu - security update

This update for QEMU, a fast processor emulator, backports support to passthrough the pschange-mc-no CPU flag. The virtualised MSR seen by a guest is set to show the bug as fixed, allowing to disable iTLB Multihit mitigations in nested hypervisors cf. DSA 4564-1. C Tenable Network Security, Inc...

RUSTSEC-2019-0025 Flaw in CBOR deserializer allows stack overflow

Affected versions of this crate did not properly check if semantic tags were nested excessively during deserialization. This allows an attacker to craft small 1 kB CBOR documents that cause a stack overflow. The flaw was corrected by limiting the allowed number of nested tags...

Kernel: KVM: nVMX: guest accesses L0 MSR causes potential DoS

A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Register MSR access with nested=1 virtualization enabled. In that, L1 guest could access L0's APIC register values via L2 guest, when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash th...
