The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
dpdk: Information exposure in unchecked guest physical to host virtual address translations (CVE-2018-1059)
A flaw was found in the vhost library in DPDK. Function vhost_user_set_inflight_fd() does not validate msg->payload.inflight.num_queues
, possibly causing out-of-bounds memory read/write. Any software using DPDK vhost library may crash as a result of this vulnerability. (CVE-2021-3839)
A flaw was found in dpdk. This flaw allows a malicious vhost-user master to attach an unexpected number of fds as ancillary data to VHOST_USER_GET_INFLIGHT_FD / VHOST_USER_SET_INFLIGHT_FD messages that are not closed by the vhost-user slave. By sending such messages continuously, the vhost-user master exhausts available fd in the vhost-user slave process, leading to a denial of service. (CVE-2022-0669)
NVIDIA’s distribution of the Data Plane Development Kit (MLNX_DPDK) contains a vulnerability in the network stack, where error recovery is not handled properly, which can allow a remote attacker to cause denial of service and some impact to data integrity and confidentiality. (CVE-2022-28199)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
