The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2011-282:05 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-2011-0726     The do_task_stat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an     expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by     reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE     binary.
    CVE-2011-1093     The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP)     implementation in the Linux kernel before 2.6.38 does not properly handle packets for a CLOSED endpoint,     which allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending     a DCCP-Close packet followed by a DCCP-Reset packet.
    CVE-2011-1170     net/ipv4/netfilter/arp_tables.c in the IPv4 implementation in the Linux kernel before 2.6.39 does not     place the expected '' character at the end of string data in the values of certain structure members,     which allows local users to obtain potentially sensitive information from kernel memory by leveraging the     CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting     modprobe process.
    CVE-2011-1171     net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux kernel before 2.6.39 does not place     the expected '' character at the end of string data in the values of certain structure members, which     allows local users to obtain potentially sensitive information from kernel memory by leveraging the     CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting     modprobe process.
    CVE-2011-1172     net/ipv6/netfilter/ip6_tables.c in the IPv6 implementation in the Linux kernel before 2.6.39 does not     place the expected '' character at the end of string data in the values of certain structure members,     which allows local users to obtain potentially sensitive information from kernel memory by leveraging the     CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting     modprobe process.
    CVE-2011-1163     The osf_partition function in fs/partitions/osf.c in the Linux kernel before 2.6.38 does not properly     handle an invalid number of partitions, which might allow local users to obtain potentially sensitive     information from kernel heap memory via vectors related to partition-table parsing.
    CVE-2011-1494     Integer overflow in the _ctl_do_mpt_command function in drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux     kernel 2.6.38 and earlier might allow local users to gain privileges or cause a denial of service (memory     corruption) via an ioctl call specifying a crafted value that triggers a heap-based buffer overflow.
    CVE-2011-1495     drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and earlier does not validate (1) length and     (2) offset values before performing memory copy operations, which might allow local users to gain     privileges, cause a denial of service (memory corruption), or obtain sensitive information from kernel     memory via a crafted ioctl call, related to the _ctl_do_mpt_command and _ctl_diag_read_buffer functions.
    CVE-2011-1577     Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38     and earlier allows physically proximate attackers to cause a denial of service (OOPS) or possibly have     unspecified other impact via a crafted size of the EFI GUID partition-table header on removable media.
