ALSA-2022:1759 — Moderate: virt:rhel and virt-devel:rhel security, bug fix, and enhancement update

Affected: AlmaLinux:8: SLOF, AlmaLinux:8: hivex, AlmaLinux:8: hivex-devel, AlmaLinux:8: libguestfs, AlmaLinux:8: libguestfs-appliance, AlmaLinux:8: libguestfs-bash-completion, AlmaLinux:8: libguestfs-devel, AlmaLinux:8: libguestfs-gfs2, AlmaLinux:8: libguestfs-gobject, AlmaLinux:8: libguestfs-gobject-devel and 120 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.

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 flaw was found in the hivex library. This flaw allows an attacker to input a specially crafted Windows Registry (hive) file, which would cause hivex to recursively call the _get_children() function, leading to a stack overflow. The highest threat from this vulnerability is to system availability.
