x86: Speculative vulnerabilities with bare (non-shim) 32-bit PV guests

ISSUE DESCRIPTION 32-bit x86 PV guest kernels run in ring 1. At the time when Xen was developed, this area of the i386 architecture was rarely used, which is why Xen was able to use it to implement paravirtualisation, Xen's novel approach to virtualization. In AMD64, Xen had to use a different...

Important: qemu

Issue Overview: A memory leakage flaw was found in the way the VNC display driver of QEMU handled the connection disconnect when ZRLE and Tight encoding are enabled. Two VncState objects are created, and one allocates memory for the Zlib's data object. This allocated memory is not freed upon...

QEMU: slirp: networking out-of-bounds read information disclosure vulnerability

An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6sendechoreply routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory,...

CVE-2020-27173

In vm-superio before 0.1.1, the serial console FIFO can grow to unlimited memory usage when data is sent to the input source i.e., standard input. This behavior cannot be reproduced from the guest side. When no rate limiting is in place, the host can be subject to memory pressure, impacting all...

CVE-2020-27173: Allocation of Resources Without Limits or Throttling

In vm-superio before 0.1.1, the serial console FIFO can grow to unlimited memory usage when data is sent to the input source i.e., standard input. This behavior cannot be reproduced from the guest side. When no rate limiting is in place, the host can be subject to memory pressure, impacting all...

CVE-2020-27174: Missing Release of Memory after Effective Lifetime

In Amazon AWS Firecracker before 0.21.3, and 0.22.x before 0.22.1, the serial console buffer can grow its memory usage without limit when data is sent to the standard input.
