"The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2014-0069 advisory.

  - The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly
    handle uncached write operations that copy fewer than the requested number of bytes, which allows local
    users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and
    system crash), or possibly gain privileges via a writev system call with a crafted pointer.
    (CVE-2014-0069)

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