ALSA-2021:3061 — Moderate: virt:rhel and virt-devel:rhel security and bug fix update

Affected: AlmaLinux:8: libguestfs-winsupport, AlmaLinux:8: libiscsi, AlmaLinux:8: libiscsi-devel, AlmaLinux:8: libiscsi-utils, AlmaLinux:8: libnbd, AlmaLinux:8: libnbd-devel, AlmaLinux:8: libvirt-dbus, AlmaLinux:8: nbdfuse, AlmaLinux:8: nbdkit, AlmaLinux:8: nbdkit-bash-completion and 25 more

Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.

Security Fix(es):

* QEMU: msix: OOB access during mmio operations may lead to DoS (CVE-2020-13754)

* hivex: Buffer overflow when provided invalid node key length (CVE-2021-3504)

* QEMU: net: an assert failure via eth_get_gso_type (CVE-2020-27617)

* QEMU: net: infinite loop in loopback mode may lead to stack overflow (CVE-2021-3416)

* qemu: out-of-bound heap buffer access via an interrupt ID field (CVE-2021-20221)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* cannot restart default network and firewalld: iptables: No chain/target/match by that name. (BZ#1958301)

* RHEL8.4 Nightly[0322] - KVM guest fails to find zipl boot menu index (qemu-kvm) (BZ#1975679)

OESA-2021-1072 — qemu security update

Affected: openEuler:20.03-LTS: qemu, openEuler:20.03-LTS-SP1: qemu

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation.(CVE-2020-13754)

In QEMU 4.1.0, an out-of-bounds read flaw was found in the ATI VGA implementation. It occurs in the ati_cursor_define() routine while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service.(CVE-2019-20808)

A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the QEMU process on the host.(CVE-2020-17380)
