The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:1759 advisory.

    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.

    The following packages have been upgraded to a later upstream version: qemu-kvm (6.2.0), libvirt (8.0.0),     libvirt-python (8.0.0), perl-Sys-Virt (8.0.0), seabios (1.15.0), libtpms (0.9.1). (BZ#1997410, BZ#2012802,     BZ#2012806, BZ#2012813, BZ#2018392, BZ#2027716, BZ#2029355)

    * ntfs-3g: Heap buffer overflow in ntfs_inode_lookup_by_name() (CVE-2021-39256)

    * ntfs-3g: Endless recursion from ntfs_attr_pwrite() triggered by an unallocated bitmap (CVE-2021-39257)

    * ntfs-3g: Out-of-bounds reads in ntfs_attr_find() and ntfs_external_attr_find() (CVE-2021-39258)

    * ntfs-3g: Out-of-bounds access in ntfs_inode_lookup_by_name() caused by an unsanitized attribute length     (CVE-2021-39259)

    * ntfs-3g: Out-of-bounds access in ntfs_inode_sync_standard_information() (CVE-2021-39260)

    * nbdkit: NBD_OPT_STRUCTURED_REPLY injection on STARTTLS (CVE-2021-3716)

    * libvirt: segmentation fault during VM shutdown can lead to vdsm hang (CVE-2021-3975)
