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

  - A NULL pointer dereference flaw was found in the floppy disk emulator of QEMU. This issue occurs while     processing read/write ioport commands if the selected floppy drive is not initialized with a block device.
    This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of     service. The highest threat from this vulnerability is to system availability. (CVE-2021-20196)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function     ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of     service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a     crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the     bytes_in_use field should be less than the bytes_allocated field. When it is not, the parsing of the     records proceeds into the wild. (CVE-2021-33285)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted unicode string is supplied in an NTFS image a     heap buffer overflow can occur and allow for code execution. (CVE-2021-33286)

  - In NTFS-3G versions < 2021.8.22, when specially crafted NTFS attributes are read in the function     ntfs_attr_pread_i, a heap buffer overflow can occur and allow for writing to arbitrary memory or denial of     service of the application. (CVE-2021-33287)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted MFT section is supplied in an NTFS image a heap     buffer overflow can occur and allow for code execution. (CVE-2021-33289)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image     a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code     execution. (CVE-2021-35266)

  - NTFS-3G versions < 2021.8.22, a stack buffer overflow can occur when correcting differences in the MFT and     MFTMirror allowing for code execution or escalation of privileges when setuid-root. (CVE-2021-35267)

  - In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode is loaded in the function     ntfs_inode_real_open, a heap buffer overflow can occur allowing for code execution and escalation of     privileges. (CVE-2021-35268)

  - NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute from the MFT is setup in the     function ntfs_attr_setup_flag, a heap buffer overflow can occur allowing for code execution and escalation     of privileges. (CVE-2021-35269)

  - 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. (CVE-2021-3622)

  - A flaw was found in nbdkit due to to improperly caching plaintext state across the STARTTLS encryption     boundary. A MitM attacker could use this flaw to inject a plaintext NBD_OPT_STRUCTURED_REPLY before     proxying everything else a client sends to the server, potentially leading the client to terminate the NBD     session. The highest threat from this vulnerability is to system availability. (CVE-2021-3716)

  - A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the     descriptor's address belongs to the non direct access region, due to num_buffers being set after the     virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a     denial of service condition, or potentially execute code on the host with the privileges of the QEMU     process. (CVE-2021-3748)

  - A crafted NTFS image can cause a NULL pointer dereference in ntfs_extent_inode_open in NTFS-3G <     2021.8.22. (CVE-2021-39251)

  - A crafted NTFS image can cause an out-of-bounds read in ntfs_ie_lookup in NTFS-3G < 2021.8.22.
    (CVE-2021-39252)

  - A crafted NTFS image can cause an out-of-bounds read in ntfs_runlists_merge_i in NTFS-3G < 2021.8.22.
    (CVE-2021-39253)

  - A crafted NTFS image can cause an integer overflow in memmove, leading to a heap-based buffer overflow in     the function ntfs_attr_record_resize, in NTFS-3G < 2021.8.22. (CVE-2021-39254)

  - A crafted NTFS image can trigger an out-of-bounds read, caused by an invalid attribute in     ntfs_attr_find_in_attrdef, in NTFS-3G < 2021.8.22. (CVE-2021-39255)

  - A crafted NTFS image can cause a heap-based buffer overflow in ntfs_inode_lookup_by_name in NTFS-3G <     2021.8.22. (CVE-2021-39256)

  - A crafted NTFS image with an unallocated bitmap can lead to a endless recursive function call chain     (starting from ntfs_attr_pwrite), causing stack consumption in NTFS-3G < 2021.8.22. (CVE-2021-39257)

  - A crafted NTFS image can cause out-of-bounds reads in ntfs_attr_find and ntfs_external_attr_find in     NTFS-3G < 2021.8.22. (CVE-2021-39258)

  - A crafted NTFS image can trigger an out-of-bounds access, caused by an unsanitized attribute length in     ntfs_inode_lookup_by_name, in NTFS-3G < 2021.8.22. (CVE-2021-39259)

  - A crafted NTFS image can cause an out-of-bounds access in ntfs_inode_sync_standard_information in NTFS-3G     < 2021.8.22. (CVE-2021-39260)

  - A crafted NTFS image can cause a heap-based buffer overflow in ntfs_compressed_pwrite in NTFS-3G <     2021.8.22. (CVE-2021-39261)

  - A crafted NTFS image can cause an out-of-bounds access in ntfs_decompress in NTFS-3G < 2021.8.22.
    (CVE-2021-39262)

  - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in     ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  - 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. (CVE-2021-3975)

  - A NULL pointer dereference issue was found in the block mirror layer of QEMU in versions prior to 6.2.0.
    The `self` pointer is dereferenced in mirror_wait_on_conflicts() without ensuring that it's not NULL. A     malicious unprivileged user within the guest could use this flaw to crash the QEMU process on the host     when writing data reaches the threshold of mirroring node. (CVE-2021-4145)

  - A NULL pointer dereference issue was found in the ACPI code of QEMU. A malicious, privileged user within     the guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service     condition. (CVE-2021-4158)

  - A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using     asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as     successful, rather than checking the *error parameter. This could result in the silent creation of a     corrupted destination image. (CVE-2022-0485)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.100173 advisory.

  - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in     ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers     option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain     unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
    (CVE-2023-45234)

  - A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may     allow an authenticated client to cause a denial of service. (CVE-2023-1667)

  - A vulnerability was found in libssh, where the authentication check of the connecting client can be     bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen     if there is insufficient memory or the memory usage is limited. The problem is caused by the return value     `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call     `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the     cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
    (CVE-2023-2283)

  - A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange     differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. (CVE-2023-5981)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in nbdkit due to to improperly caching plaintext state across the STARTTLS encryption     boundary. A MitM attacker could use this flaw to inject a plaintext NBD_OPT_STRUCTURED_REPLY before     proxying everything else a client sends to the server, potentially leading the client to terminate the NBD     session. The highest threat from this vulnerability is to system availability. (CVE-2021-3716)

Note that Nessus relies on the presence of the package as reported by the vendor.

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

  - QEMU: NULL pointer dereference in mirror_wait_on_conflicts() in block/mirror.c (CVE-2021-4145)

  - QEMU: NULL pointer dereference in pci_write() in hw/acpi/pcihp.c (CVE-2021-4158)

  - libnbd: nbdcopy: missing error handling may create corrupted destination image (CVE-2022-0485)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.101026 advisory.

  - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in     ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers     option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain     unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
    (CVE-2023-45234)

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote     attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the     KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the     protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG     records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)     allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC     responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an     algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)
