The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:1762 advisory.

  - iscsi_aio_ioctl_cb in block/iscsi.c in QEMU 4.1.0 has a heap-based buffer over-read that may disclose     unrelated information from process memory to an attacker. (CVE-2020-11947)

  - In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects     the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the     QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in     hw/net/net_tx_pkt.c. (CVE-2020-16092)

  - A double free memory issue was found to occur in the libvirt API, in versions before 6.8.0, responsible     for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit     access control driver. Specifically, clients connecting to the read-write socket with limited ACL     permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or     potentially escalate their privileges on the system. The highest threat from this vulnerability is to data     confidentiality and integrity as well as system availability. (CVE-2020-25637)

  - A reachable assertion issue was found in the USB EHCI emulation code of QEMU. It could occur while     processing USB requests due to missing handling of DMA memory map failure. A malicious privileged user     within the guest may abuse this flaw to send bogus USB requests and crash the QEMU process on the host,     resulting in a denial of service. (CVE-2020-25723)

  - A flaw was found in the memory management API of QEMU during the initialization of a memory region cache.
    This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO     operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial     of service. This flaw affects QEMU versions prior to 5.2.0. (CVE-2020-27821)

  - hw/net/e1000e_core.c in QEMU 5.0.0 has an infinite loop via an RX descriptor with a NULL buffer address.
    (CVE-2020-28916)

  - ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of     header data even if that exceeds the total packet length. (CVE-2020-29129)

  - slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of     header data even if that exceeds the total packet length. (CVE-2020-29130)

  - ide_atapi_cmd_reply_end in hw/ide/atapi.c in QEMU 5.1.0 allows out-of-bounds read access because a buffer     index is not validated. (CVE-2020-29443)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES11 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14772-1 advisory.

  - iscsi_aio_ioctl_cb in block/iscsi.c in QEMU 4.1.0 has a heap-based buffer over-read that may disclose     unrelated information from process memory to an attacker. (CVE-2020-11947)

  - In QEMU 4.2.0, a MemoryRegionOps object may lack read/write callback methods, leading to a NULL pointer     dereference. (CVE-2020-15469)

  - hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This     occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or     process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or     potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555.
    (CVE-2020-15863)

  - An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of     QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an     interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said     issue while updating controller state fields and their subsequent processing. A privileged guest user may     use this flaw to crash the QEMU process on the host resulting in DoS scenario. (CVE-2021-20221)

  - A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions     up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get     bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the     host resulting in DoS scenario. (CVE-2021-3416)

  - An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw     exists in the bootp_input() function and could occur while processing a udp packet that is smaller than     the size of the 'bootp_t' structure. A malicious guest could use this flaw to leak 10 bytes of     uninitialized heap memory from the host. The highest threat from this vulnerability is to data     confidentiality. This flaw affects libslirp versions prior to 4.6.0. (CVE-2021-3592)

  - An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw     exists in the udp_input() function and could occur while processing a udp packet that is smaller than the     size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory     disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw     affects libslirp versions prior to 4.6.0. (CVE-2021-3594)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of qemu installed on the remote host is prior to 3.1.0-8. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1671 advisory.

    A heap buffer overflow flaw was found in the iSCSI support of QEMU. This flaw could lead to an out-of-     bounds read access and possible information disclosure from the QEMU process memory to a malicious guest.
    The highest threat from this vulnerability is to data confidentiality. (CVE-2020-11947)

    An infinite loop flaw was found in the e1000e NIC emulation code of QEMU. This issue occurs in the     e1000e_write_packet_to_guest() routine while processing bogus RX descriptor data transmitted by the guest.
    This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of     service. (CVE-2020-25707)

    A reachable assertion vulnerability was found in the USB EHCI emulation code of QEMU. This issue occurs     while processing USB requests due to missed handling of DMA memory map failure. This flaw allows a     malicious privileged user within the guest to send bogus USB requests and crash the QEMU process on the     host, resulting in a denial of service. The highest threat from this vulnerability is to system     availability. (CVE-2020-25723)

    A flaw was found in the memory management API of QEMU during the initialization of a memory region cache.
    This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO     operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial     of service. (CVE-2020-27821)

    An out-of-bounds access issue was found in the SLiRP user networking implementation of QEMU. It could     occur while processing ARP/NCSI packets, if the packet length was shorter than required to accommodate     respective protocol headers and payload. A privileged guest user may use this flaw to potentially leak     host information bytes. (CVE-2020-29129)

    An out-of-bounds access issue was found in the SLiRP user networking implementation of QEMU. It could     occur while processing ARP/NCSI packets, if the packet length was shorter than required to accommodate     respective protocol headers and payload. A privileged guest user may use this flaw to potentially leak     host information bytes. (CVE-2020-29130)

    An out-of-bounds read-access flaw was found in the ATAPI Emulator of QEMU. This issue occurs while     processing the ATAPI read command if the logical block address(LBA) is set to an invalid value. A guest     user may use this flaw to crash the QEMU process on the host resulting in a denial of service.
