    * ntfs-3g: Out-of-bounds read in ntfs_runlists_merge_i() (CVE-2021-39253)

    * ntfs-3g: Integer overflow in memmove() leading to heap buffer overflow in ntfs_attr_record_resize()     (CVE-2021-39254)

    * ntfs-3g: Out-of-bounds read ntfs_attr_find_in_attrdef() triggered by an invalid attribute     (CVE-2021-39255)

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

    * 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)

    * ntfs-3g: Heap buffer overflow in ntfs_compressed_pwrite() (CVE-2021-39261)

    * ntfs-3g: Out-of-bounds access in ntfs_decompress() (CVE-2021-39262)

    * ntfs-3g: Heap buffer overflow in ntfs_get_attribute_value() caused by an unsanitized attribute     (CVE-2021-39263)

    * QEMU: net: Infinite loop in loopback mode may lead to stack overflow (CVE-2021-3416)

    * libvirt: Insecure sVirt label generation (CVE-2021-3631)

    * libvirt: Improper locking on ACL failure in virStoragePoolLookupByTargetPath API (CVE-2021-3667)
