An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack by causing the libvirt daemon to crash.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-12605 advisory.

According to the versions of the libvirt package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number     of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially     crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack     by causing the libvirt daemon to crash.(CVE-2024-1441)

    A NULL pointer dereference flaw was found in the udevConnectListAllInterfaces() function in libvirt. This     issue can occur when detaching a host interface while at the same time collecting the list of interfaces     via virConnectListAllInterfaces API. This flaw could be used to perform a denial of service attack by     causing the libvirt daemon to crash.(CVE-2024-2496)

    While the C API entry points will validate non-negative lengths for various parameters, the RPC server de-     serialization code will need to allocate memory for arrays before entering the C API. These allocations     will thus happen before the non-negative length check is performed.  Passing a negative length to the     g_new0 function will usually result in a crash due to the negative length being treated as a huge positive     number.  This was found and diagnosed by ALT Linux Team with AFLplusplus.(CVE-2024-2494)

    A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in     the virNetClientIOEventLoop() method, the data pointer to a stack-allocated virNetClientIOEventData     structure ended up being used in the virNetClientIOEventFD callback while the data pointer s stack frame     was concurrently being freed when returning from virNetClientIOEventLoop(). The virtproxyd daemon can be     used to trigger requests. If libvirt is configured with fine-grained access control, this issue, in     theory, allows a user to escape their otherwise limited access. This flaw allows a local, unprivileged     user to access virtproxyd without authenticating. Remote users would need to authenticate before they     could access it.(CVE-2024-4418)

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

  - An improper locking issue was found in the virStoragePoolLookupByTargetPath API of libvirt. It occurs in     the storagePoolLookupByTargetPath function where a locked virStoragePoolObj object is not properly     released on ACL permission failure. Clients connecting to the read-write socket with limited ACL     permissions could use this flaw to acquire the lock and prevent other users from accessing storage     pool/volume APIs, resulting in a denial of service condition. The highest threat from this vulnerability     is to system availability. (CVE-2021-3667)

  - 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)

  - An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number     of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially     crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack     by causing the libvirt daemon to crash. (CVE-2024-1441)

  - A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The     qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the     chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a     malicious authenticated VNC client to crash QEMU and trigger a denial of service. (CVE-2023-6683)

  - QEMU through 8.0.0 could trigger a division by zero in scsi_disk_reset in hw/scsi/scsi-disk.c because     scsi_disk_emulate_mode_select does not prevent s->qdev.blocksize from being 256. This stops QEMU and the     guest immediately. (CVE-2023-42467)

  - A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be     targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for     example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor     to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
    (CVE-2023-5088)

  - A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the     Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be     written to the controller's registers and trigger undesirable actions (such as reset) while the device is     still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could     use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or     potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects     QEMU versions before 7.0.0. (CVE-2021-3750)

  - A DMA reentrancy issue leading to a use-after-free error was found in the e1000e NIC emulation code in     QEMU. This issue could allow a privileged guest user to crash the QEMU process on the host, resulting in a     denial of service. (CVE-2023-3019)

  - QEMU before 8.2.0 has an integer underflow, and resultant buffer overflow, via a TI command when an     expected non-DMA transfer length is less than the length of the available FIFO data. This occurs in     esp_do_nodma in hw/scsi/esp.c because of an underflow of async_len. (CVE-2024-24474)

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1099-1 advisory.

  - An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number     of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially     crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack     by causing the libvirt daemon to crash. (CVE-2024-1441)

  - A flaw was found in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory     for arrays before the non-negative length check is performed by the C API entry points. Passing a negative     length to the g_new0 function results in a crash due to the negative length being treated as a huge     positive number. This flaw allows a local, unprivileged user to perform a denial of service attack by     causing the libvirt daemon to crash. (CVE-2024-2494)

  - A NULL pointer dereference flaw was found in the udevConnectListAllInterfaces() function in libvirt. This     issue can occur when detaching a host interface while at the same time collecting the list of interfaces     via virConnectListAllInterfaces API. This flaw could be used to perform a denial of service attack by     causing the libvirt daemon to crash. (CVE-2024-2496)

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

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3778 advisory.

  - A NULL pointer dereference was found in the libvirt API responsible introduced in upstream version 3.10.0,     and fixed in libvirt 6.0.0, for fetching a storage pool based on its target path. In more detail, this     flaw affects storage pools created without a target path such as network-based pools like gluster and RBD.
    Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon,     resulting in a potential denial of service. (CVE-2020-10703)

  - An issue was discovered in qemuDomainGetStatsIOThread in qemu/qemu_driver.c in libvirt 4.10.0 though 6.x     before 6.1.0. A memory leak was found in the virDomainListGetStats libvirt API that is responsible for     retrieving domain statistics when managing QEMU guests. This flaw allows unprivileged users with a read-     only connection to cause a memory leak in the domstats command, resulting in a potential denial of     service. (CVE-2020-12430)

  - A double free memory issue was found to occur in the libvirt API, in versions before 6.8.0, responsible     for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit     access control driver. Specifically, clients connecting to the read-write socket with limited ACL     permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or     potentially escalate their privileges on the system. The highest threat from this vulnerability is to data     confidentiality and integrity as well as system availability. (CVE-2020-25637)

  - A flaw was found in libvirt while it generates SELinux MCS category pairs for VMs' dynamic labels. This     flaw allows one exploited guest to access files labeled for another guest, resulting in the breaking out     of sVirt confinement. The highest threat from this vulnerability is to confidentiality and integrity.
    (CVE-2021-3631)

  - An improper locking issue was found in the virStoragePoolLookupByTargetPath API of libvirt. It occurs in     the storagePoolLookupByTargetPath function where a locked virStoragePoolObj object is not properly     released on ACL permission failure. Clients connecting to the read-write socket with limited ACL     permissions could use this flaw to acquire the lock and prevent other users from accessing storage     pool/volume APIs, resulting in a denial of service condition. The highest threat from this vulnerability     is to system availability. (CVE-2021-3667)

  - 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 flaw was found in the libvirt libxl driver. A malicious guest could continuously reboot itself and cause     libvirtd on the host to deadlock or crash, resulting in a denial of service condition. (CVE-2021-4147)

  - A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to     acquire the driver->nwfilters mutex before iterating over virNWFilterObj instances. There was no     protection to stop another thread from concurrently modifying the driver->nwfilters object. This flaw     allows a malicious, unprivileged user to exploit this issue via libvirt's API virConnectNumOfNWFilters to     crash the network filter management daemon (libvirtd/virtnwfilterd). (CVE-2022-0897)

  - An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number     of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially     crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack     by causing the libvirt daemon to crash.
