The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5881 advisory.

  - Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow     attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout()     failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the     htc_connect_service() function, aka CID-853acf7caf10. (CVE-2019-19073)

  - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file     system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash     the system if the directory exists. The highest threat from this vulnerability is to system availability.
    (CVE-2020-14314)

  - The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows     local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer     underflow. (CVE-2017-8924)

  - A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be     used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified     other impact, aka CID-17743798d812. (CVE-2020-25285)

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

The remote Redhat Enterprise Linux 6 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.

  - kernel: Buffer overflow due to unbounded strcpy in ISDN I4L driver (CVE-2017-12762)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - include/linux/init_task.h in the Linux kernel before 2.6.35 does not prevent signals with a process group     ID of zero from reaching the swapper process, which allows local users to cause a denial of service     (system crash) by leveraging access to this process group. (CVE-2010-5328)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 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.

  - kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c     (CVE-2017-18017)

  - The ia64 subsystem in the Linux kernel before 2.6.26 allows local users to cause a denial of service     (stack consumption and system crash) via a crafted application that leverages the mishandling of invalid     Register Stack Engine (RSE) state. (CVE-2006-3635)

  - drivers/media/video/videobuf-vmalloc.c in the Linux kernel before 2.6.24 does not initialize     videobuf_mapping data structures, which allows local users to trigger an incorrect count value and     videobuf leak via unspecified vectors, a different vulnerability than CVE-2010-5321. (CVE-2007-6761)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
