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)

Security Fix(es):

* QEMU: virtio-net: heap use-after-free in virtio_net_receive_rcu (CVE-2021-3748)

* ntfs-3g: Out-of-bounds heap buffer access in ntfs_get_attribute_value() due to incorrect check of bytes_in_use value in MFT records (CVE-2021-33285)

* ntfs-3g: Heap buffer overflow triggered by a specially crafted Unicode string (CVE-2021-33286)

* ntfs-3g: Heap buffer overflow in ntfs_attr_pread_i() triggered by specially crafted NTFS attributes (CVE-2021-33287)

* ntfs-3g: Heap buffer overflow triggered by a specially crafted MFT section (CVE-2021-33289)

* ntfs-3g: Heap buffer overflow triggered by a specially crafted NTFS inode pathname (CVE-2021-35266)

* ntfs-3g: Stack buffer overflow triggered when correcting differences between MFT and MFTMirror sections (CVE-2021-35267)

* ntfs-3g: Heap buffer overflow in ntfs_inode_real_open() triggered by a specially crafted NTFS inode (CVE-202…

A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash.
