"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2013-97:01 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel
    handles the basic functions of the operating system: memory allocation, process allocation, device input
    and output, etc.
    Security issues fixed with this release:
     CVE-2012-2100
    The ext4_fill_flex_info function in fs/ext4/super.c in the Linux kernel before 3.2.2, on the x86 platform
    and unspecified other platforms, allows user-assisted remote attackers to trigger inconsistent filesystem-
    groups data and possibly cause a denial of service via a malformed ext4 filesystem containing a super
    block with a large FLEX_BG group size (aka s_log_groups_per_flex value). NOTE: this vulnerability exists
    because of an incomplete fix for CVE-2009-4307.
     CVE-2012-2375
    The __nfs4_get_acl_uncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel
    before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to
    cause a denial of service (OOPS) by sending an excessive number of bitmap words in an FATTR4_ACL reply.
    NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-4131.
     CVE-2012-4444
    The ip6_frag_queue function in net/ipv6/reassembly.c in the Linux kernel before 2.6.36 allows remote
    attackers to bypass intended network restrictions via overlapping IPv6 fragments.
     CVE-2012-4565
    The tcp_illinois_info function in net/ipv4/tcp_illinois.c in the Linux kernel before 3.4.19, when the
    net.ipv4.tcp_congestion_control illinois setting is enabled, allows local users to cause a denial of
    service (divide-by-zero error and OOPS) by reading TCP stats.
     CVE-2012-5517
    The online_pages function in mm/memory_hotplug.c in the Linux kernel before 3.6 allows local users to
    cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other
    impact in opportunistic circumstances by using memory that was hot-added by an administrator.

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

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