"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2012-646:05 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-2012-1601
    The KVM implementation in the Linux kernel before 3.3.6 allows host OS users to cause a denial of service
    (NULL pointer dereference and host OS crash) by making a KVM_CREATE_IRQCHIP ioctl call after a virtual CPU
    already exists.
     CVE-2012-0044
    Integer overflow in the drm_mode_dirtyfb_ioctl function in drivers/gpu/drm/drm_crtc.c in the Direct
    Rendering Manager (DRM) subsystem in the Linux kernel before 3.1.5 allows local users to gain privileges
    or cause a denial of service (memory corruption) via a crafted ioctl call.
     CVE-2012-1179
    psThe Linux kernel before 3.3.1, when KVM is used, allows guest OS users to cause a denial of service
    (host OS crash) by leveraging administrative access to the guest OS, related to the pmd_none_or_clear_bad
    function and page faults for huge pages.
     CVE-2012-2121
    The KVM implementation in the Linux kernel before 3.3.4 does not properly anage the relationships between
    memory slots and the iommu, which allows guest OS users to cause a denial of service (host OS crash) by
    leveraging administrative access to the guest OS to conduct hotunplug and hotplug operations on devices.
     CVE-2012-2123
    The cap_bprm_set_creds function in security/commoncap.c in the Linux kernel before 3.3.3 does not properly
    handle the use of file system capabilities (aka fcaps) for implementing a privileged executable file,
    which allows local users to bypass intended personality restrictions via a crafted application, as
    demonstrated by an attack that uses a parent process to disable ASLR.
     CVE-2012-2136
     CVE-2012-2137
     CVE-2012-2372
     CVE-2012-2373
