"The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2017-2299:08 advisory.

    * A stack buffer overflow flaw was found in the way the Bluetooth subsystem of
    the Linux kernel processed pending L2CAP configuration responses from a client.
    On systems with the stack protection feature enabled in the kernel
    (CONFIG_CC_STACKPROTECTOR=y, which is enabled on all architectures other than
    s390x and ppc64[le]), an unauthenticated attacker able to initiate a connection
    to a system via Bluetooth could use this flaw to crash the system. Due to the
    nature of the stack protection feature, code execution cannot be fully ruled
    out, although we believe it is unlikely. On systems without the stack protection
    feature (ppc64[le]; the Bluetooth modules are not built on s390x), an
    unauthenticated attacker able to initiate a connection to a system via Bluetooth
    could use this flaw to remotely execute arbitrary code on the system with ring 0
    (kernel) privileges. (CVE-2017-1000251, Important)
    Asianux would like to thank Armis Labs for reporting this issue.
    CVE-2017-1000251
    The native Bluetooth stack in the Linux Kernel (BlueZ), starting at
    the Linux kernel version 3.3-rc1 and up to and including 4.13.1, are
    vulnerable to a stack overflow vulnerability in the processing of
    L2CAP configuration responses resulting in Remote code execution in
    kernel space.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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