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):
* ntfs-3g: heap-based buffer overflow in ntfsck (CVE-2021-46790)
* QEMU: VNC: integer underflow in vnc_client_cut_text_ext leads to CPU
exhaustion (CVE-2022-3165)
* ntfs-3g: crafted NTFS image can cause heap exhaustion in
ntfs_get_attribute_value (CVE-2022-30784)
* ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in
ntfs_names_full_collate (CVE-2022-30786)
* ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in
ntfs_mft_rec_alloc (CVE-2022-30788)
* ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in
ntfs_check_log_client_array (CVE-2022-30789)
* tpm2: TCG TPM2.0 implementations vulnerable to memory corruption
(CVE-2023-1018)
