"The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2019:14127-1 advisory.

  - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout()
    and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)

  - Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and
    tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. (CVE-2018-5390)

  - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux
    kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause
    a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)

  - A heap address information leak while using L2CAP_GET_CONF_OPT was discovered in the Linux kernel before
    5.1-rc1. (CVE-2019-3459)

  - A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found in the Linux kernel
    before 5.1-rc1. (CVE-2019-3460)

  - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the
    mwifiex kernel module while connecting to a malicious wireless network. (CVE-2019-3846)

  - A double-free can happen in idr_remove_all() in lib/idr.c in the Linux kernel 2.6 branch. An unprivileged
    local attacker can use this flaw for a privilege escalation or for a system crash and a denial of service
    (DoS). (CVE-2019-3896)

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