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.
