Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5642 advisory.- The swiotlb_print_info function in lib/swiotlb.c in the Linux kernel through 4.14.14 allows local users to obtain sensitive address information by reading dmesg data from a software IO TLB printk call.
(CVE-2018-5953)
- In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
(CVE-2020-10942)
- A memory leak in the ql_alloc_large_buffers() function in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux kernel before 5.3.5 allows local users to cause a denial of service (memory consumption) by triggering pci_dma_mapping_error() failures, aka CID-1acb8f2a7a9f. (CVE-2019-18806)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
