The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - QEMU: net: ignore packets with large size (CVE-2018-17963)

  - Buffer overflow in the send_control_msg function in hw/char/virtio-serial-bus.c in QEMU before 2.4.0     allows guest users to cause a denial of service (QEMU process crash) via a crafted virtio control message.
    (CVE-2015-5745)

  - The MSI-X MMIO support in hw/pci/msix.c in QEMU (aka Quick Emulator) allows local guest OS privileged     users to cause a denial of service (NULL pointer dereference and QEMU process crash) by leveraging failure     to define the .write method. (CVE-2015-7549)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - QEMU: ppc64: sPAPR emulator leaks the host hardware identity (CVE-2019-8934)

  - The ahci_commit_buf function in ide/ahci.c in QEMU allows attackers to cause a denial of service (NULL     dereference) when the command header 'ad->cur_cmd' is null. (CVE-2019-12067)

  - hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check     before an ide_cancel_dma_sync call. (CVE-2020-25743)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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.
