"The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in
the USN-2359-1 advisory.

  - The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the
    number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a
    denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a
    large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn
    value that leads to permanently pinned pages. (CVE-2014-3601)

  - The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP
    authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference
    and OOPS) by starting to establish an association between two endpoints immediately after an exchange of
    INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite
    direction. (CVE-2014-5077)

  - Stack consumption vulnerability in the parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the
    Linux kernel through 3.16.1 allows local users to cause a denial of service (uncontrolled recursion, and
    system crash or reboot) via a crafted iso9660 image with a CL entry referring to a directory entry that
    has a CL entry. (CVE-2014-5471)

  - The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows
    local users to cause a denial of service (unkillable mount process) via a crafted iso9660 image with a
    self-referential CL entry. (CVE-2014-5472)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
