Security update for qemu

This update for qemu fixes the following issues:

Security issues fixed:

  • CVE-2019-9824: Fixed an information leak in slirp (bsc#1129622)
  • CVE-2019-8934: Added method to specify whether or not to expose certain ppc64 host information, which can be considered a security issue (bsc#1126455)
  • CVE-2019-3812: Fixed OOB memory access and information leak in virtual monitor interface (bsc#1125721)
  • CVE-2018-20815: Fix DOS possibility in device tree processing (bsc#1130675)
  • Adjust fix for CVE-2019-8934 (bsc#1126455) to match the latest upstream adjustments for the same. Basically now the security fix is to provide a dummy host-model and host-serial value, which overrides getting that value from the host
  • CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091: Added x86 cpu feature 'md-clear' (bsc#1111331)

Other bugs fixed:

  • Use a new approach to handling the file input to -smbios option, which accepts either legacy or per-spec formats regardless of the machine type.

This update was imported from the SUSE:SLE-15:Update update project.

In QEMU 3.1.0, load_device_tree in device_tree.c calls the deprecated load_image function, which has a buffer overflow risk.

Описание

QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host.

Описание

hw/ppc/spapr.c in QEMU through 3.1.0 allows Information Exposure because the hypervisor shares the /proc/device-tree/system-id and /proc/device-tree/model system attributes with a guest.

tcp_emu in slirp/tcp_subr.c (aka slirp/src/tcp_subr.c) in QEMU 3.0.0 uses uninitialized data in an snprintf call, leading to Information disclosure.
