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.
    CVE-2010-4346     The install_special_mapping function in mm/mmap.c in the Linux kernel before 2.6.37-rc6 does not make an     expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr     restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language     application.
    CVE-2011-0521     The dvb_ca_ioctl function in drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel before 2.6.38-rc2     does not check the sign of a certain integer field, which allows local users to cause a denial of service     (memory corruption) or possibly have unspecified other impact via a negative value.
    CVE-2011-0710     The task_show_regs function in arch/s390/kernel/traps.c in the Linux kernel before     2.6.38-rc4-next-20110216 on the s390 platform allows local users to obtain the values of the registers of     an arbitrary process by reading a status file under /proc/.
    CVE-2011-1010     Buffer overflow in the mac_partition function in fs/partitions/mac.c in the Linux kernel before 2.6.37.2     allows local users to cause a denial of service (panic) or possibly have unspecified other impact via a     malformed Mac OS partition table.
    CVE-2011-1090     The __nfs4_proc_set_acl function in fs/nfs/nfs4proc.c in the Linux kernel before 2.6.38 stores NFSv4 ACL     data in memory that is allocated by kmalloc but not properly freed, which allows local users to cause a     denial of service (panic) via a crafted attempt to set an ACL.
    CVE-2010-4249     The wait_for_unix_gc function in net/unix/garbage.c in the Linux kernel before 2.6.37-rc3-next-20101125     does not properly select times for garbage collection of inflight sockets, which allows local users to     cause a denial of service (system hang) via crafted use of the socketpair and sendmsg system calls for     SOCK_SEQPACKET sockets.
    CVE-2010-4251     The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a     backlog of received packets, which allows remote attackers to cause a denial of service (memory     consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.
    CVE-2010-4655     net/core/ethtool.c in the Linux kernel before 2.6.36 does not initialize certain data structures, which     allows local users to obtain potentially sensitive information from kernel heap memory by leveraging the     CAP_NET_ADMIN capability for an ethtool ioctl call.
    CVE-2010-4526     Race condition in the Linux kernel 2.6.11-rc2 through 2.6.33 allows remote attackers to cause a denial of     service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes     the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function.
    CVE-2010-3296     The cxgb_extension_ioctl function in drivers/net/cxgb3/cxgb3_main.c in the Linux kernel before 2.6.36-rc5     does not properly initialize a certain structure member, which allows local users to obtain potentially     sensitive information from kernel stack memory via a CHELSIO_GET_QSET_NUM ioctl call.
    CVE-2010-3877     The get_name function in net/tipc/socket.c in the Linux kernel before 2.6.37-rc2 does not initialize a     certain structure, which allows local users to obtain potentially sensitive information from kernel stack     memory by reading a copy of this structure.
    CVE-2010-4072     The copy_shmid_to_user function in ipc/shm.c in the Linux kernel before 2.6.37-rc1 does not initialize a     certain structure, which allows local users to obtain potentially sensitive information from kernel stack     memory via vectors related to the shmctl system call and the old shm interface.
    CVE-2010-4073     The ipc subsystem in the Linux kernel before 2.6.37-rc1 does not initialize certain structures, which     allows local users to obtain potentially sensitive information from kernel stack memory via vectors     related to the (1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl functions in     ipc/compat.c; and the (4) compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in     ipc/compat_mq.c.
    CVE-2010-4075     The uart_get_count function in drivers/serial/serial_core.c in the Linux kernel before 2.6.37-rc1 does not     properly initialize a certain structure member, which allows local users to obtain potentially sensitive     information from kernel stack memory via a TIOCGICOUNT ioctl call.
    CVE-2010-4080     The snd_hdsp_hwdep_ioctl function in sound/pci/rme9652/hdsp.c in the Linux kernel before 2.6.36-rc6 does     not initialize a certain structure, which allows local users to obtain potentially sensitive information     from kernel stack memory via an SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctl call.
    CVE-2010-4081     The snd_hdspm_hwdep_ioctl function in sound/pci/rme9652/hdspm.c in the Linux kernel before 2.6.36-rc6 does     not initialize a certain structure, which allows local users to obtain potentially sensitive information     from kernel stack memory via an SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl call.
    CVE-2010-4158     The sk_run_filter function in net/core/filter.c in the Linux kernel before 2.6.36.2 does not check whether     a certain memory location has been initialized before executing a (1) BPF_S_LD_MEM or (2) BPF_S_LDX_MEM     instruction, which allows local users to obtain potentially sensitive information from kernel stack memory     via a crafted socket filter.
    CVE-2010-4238     The vbd_create function in Xen 3.1.2, when the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 is     used, allows guest OS users to cause a denial of service (host OS panic) via an attempted access to a     virtual CD-ROM device through the blkback driver. NOTE: some of these details are obtained from third     party information.
    CVE-2010-4243     fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory     by arrays representing the (1) arguments and (2) environment, which allows local users to cause a denial     of service (memory consumption) via a crafted exec system call, aka an OOM dodging issue, a related issue     to CVE-2010-3858.
    CVE-2010-4255     The fixup_page_fault function in arch/x86/traps.c in Xen 4.0.1 and earlier on 64-bit platforms, when     paravirtualization is enabled, does not verify that kernel mode is used to call the     handle_gdt_ldt_mapping_fault function, which allows guest OS users to cause a denial of service (host OS     BUG_ON) via a crafted memory access.
    CVE-2010-4263     The igb_receive_skb function in drivers/net/igb/igb_main.c in the Intel Gigabit Ethernet (aka igb)     subsystem in the Linux kernel before 2.6.34, when Single Root I/O Virtualization (SR-IOV) and promiscuous     mode are enabled but no VLANs are registered, allows remote attackers to cause a denial of service (NULL     pointer dereference and panic) and possibly have unspecified other impact via a VLAN tagged frame.
    CVE-2010-4343     drivers/scsi/bfa/bfa_core.c in the Linux kernel before 2.6.35 does not initialize a certain port data     structure, which allows local users to cause a denial of service (system crash) via read operations on an     fc_host statistics file.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2011-143:02 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-2010-3296     The cxgb_extension_ioctl function in drivers/net/cxgb3/cxgb3_main.c in the Linux kernel before 2.6.36-rc5     does not properly initialize a certain structure member, which allows local users to obtain potentially     sensitive information from kernel stack memory via a CHELSIO_GET_QSET_NUM ioctl call.
    CVE-2010-3877     The get_name function in net/tipc/socket.c in the Linux kernel before 2.6.37-rc2 does not initialize a     certain structure, which allows local users to obtain potentially sensitive information from kernel stack     memory by reading a copy of this structure.
    CVE-2010-4072     The copy_shmid_to_user function in ipc/shm.c in the Linux kernel before 2.6.37-rc1 does not initialize a     certain structure, which allows local users to obtain potentially sensitive information from kernel stack     memory via vectors related to the shmctl system call and the 'old shm interface.'     CVE-2010-4073     The ipc subsystem in the Linux kernel before 2.6.37-rc1 does not initialize certain structures, which     allows local users to obtain potentially sensitive information from kernel stack memory via vectors     related to the (1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl functions in     ipc/compat.c; and the (4) compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in     ipc/compat_mq.c.
    CVE-2010-4075     The uart_get_count function in drivers/serial/serial_core.c in the Linux kernel before 2.6.37-rc1 does not     properly initialize a certain structure member, which allows local users to obtain potentially sensitive     information from kernel stack memory via a TIOCGICOUNT ioctl call.
    CVE-2010-4080     The snd_hdsp_hwdep_ioctl function in sound/pci/rme9652/hdsp.c in the Linux kernel before 2.6.36-rc6 does     not initialize a certain structure, which allows local users to obtain potentially sensitive information     from kernel stack memory via an SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctl call.
    CVE-2010-4081     The snd_hdspm_hwdep_ioctl function in sound/pci/rme9652/hdspm.c in the Linux kernel before 2.6.36-rc6 does     not initialize a certain structure, which allows local users to obtain potentially sensitive information     from kernel stack memory via an SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl call.
    CVE-2010-4158     The sk_run_filter function in net/core/filter.c in the Linux kernel before 2.6.36.2 does not check whether     a certain memory location has been initialized before executing a (1) BPF_S_LD_MEM or (2) BPF_S_LDX_MEM     instruction, which allows local users to obtain potentially sensitive information from kernel stack memory     via a crafted socket filter.
    CVE-2010-4238     The vbd_create function in Xen 3.1.2, when the Linux kernel 2.6.18 on Asianux Server 3 is used, allows     guest OS users to cause a denial of service (host OS panic) via an attempted access to a virtual CD-ROM     device through the blkback driver. NOTE: some of these details are obtained from third party information.
    CVE-2010-4243     fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory     by arrays representing the (1) arguments and (2) environment, which allows local users to cause a denial     of service (memory consumption) via a crafted exec system call, aka an OOM dodging issue, a related issue     to CVE-2010-3858.
    CVE-2010-4255     The fixup_page_fault function in arch/x86/traps.c in Xen 4.0.1 and earlier on 64-bit platforms, when     paravirtualization is enabled, does not verify that kernel mode is used to call the     handle_gdt_ldt_mapping_fault function, which allows guest OS users to cause a denial of service (host OS     BUG_ON) via a crafted memory access.
    CVE-2010-4263     The igb_receive_skb function in drivers/net/igb/igb_main.c in the Intel Gigabit Ethernet (aka igb)     subsystem in the Linux kernel before 2.6.34, when Single Root I/O Virtualization (SR-IOV) and promiscuous     mode are enabled but no VLANs are registered, allows remote attackers to cause a denial of service (NULL     pointer dereference and panic) and possibly have unspecified other impact via a VLAN tagged frame.
    CVE-2010-4343     drivers/scsi/bfa/bfa_core.c in the Linux kernel before 2.6.35 does not initialize a certain port data     structure, which allows local users to cause a denial of service (system crash) via read operations on an     fc_host statistics file.
    CVE-2010-4526     Race condition in the Linux kernel 2.6.11-rc2 through 2.6.33 allows remote attackers to cause a denial of     service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes     the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function.
    CVE-2010-4249     The wait_for_unix_gc function in net/unix/garbage.c in the Linux kernel before 2.6.37-rc3-next-20101125     does not properly select times for garbage collection of inflight sockets, which allows local users to     cause a denial of service (system hang) via crafted use of the socketpair and sendmsg system calls for     SOCK_SEQPACKET sockets.
    CVE-2010-4251     CVE-2010-4655     No information available at the time of writing, please refer to the CVE links below.
    Fixed bugs:
     - An off-by-one error would make gfs2_grow fail to take the very last 'rgrp' parameter into account when     adding up the new free space. This has been fixed and the GFS2 kernel properly counts all the new resource     groups and fixes the 'statfs' file correctly.
     - Previously, a multi-threaded application internally invoking popen(3) could cause a thread stall by     FILE lock corruption. The lock  corruption was due to a race condition in the Copy on Write (COW) logic.
    This has been fixed.
     - If an error occurred during I/O, the SCSI driver reset the 'megaraid_sas' controller to restore it to     normal state. However, on Asianux Server 3, the waiting time to allow a full reset completion for the     'megaraid_sas' controller was too short, causing the driver to incorrectly recognize the the controller as     stalled, and in turn the system would stall too. This has been fixed by giving more time to the controller     to restart.

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 number.

Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 5. This is the sixth regular update.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* A NULL pointer dereference flaw was found in the igb driver in the Linux kernel. If both the Single Root I/O Virtualization (SR-IOV) feature and promiscuous mode were enabled on an interface using igb, it could result in a denial of service when a tagged VLAN packet is received on that interface. (CVE-2010-4263, Important)

* A missing sanity check was found in vbd_create() in the Xen hypervisor implementation. As CD-ROM drives are not supported by the blkback back-end driver, attempting to use a virtual CD-ROM drive with blkback could trigger a denial of service (crash) on the host system running the Xen hypervisor. (CVE-2010-4238, Moderate)

* A flaw was found in the Linux kernel execve() system call implementation. A local, unprivileged user could cause large amounts of memory to be allocated but not visible to the OOM (Out of Memory) killer, triggering a denial of service. (CVE-2010-4243, Moderate)

* A flaw was found in fixup_page_fault() in the Xen hypervisor implementation. If a 64-bit para-virtualized guest accessed a certain area of memory, it could cause a denial of service on the host system running the Xen hypervisor. (CVE-2010-4255, Moderate)

* A missing initialization flaw was found in the bfa driver used by Brocade Fibre Channel Host Bus Adapters. A local, unprivileged user could use this flaw to cause a denial of service by reading a file in the '/sys/class/fc_host/host#/statistics/' directory. (CVE-2010-4343, Moderate)

* Missing initialization flaws in the Linux kernel could lead to information leaks. (CVE-2010-3296, CVE-2010-3877, CVE-2010-4072, CVE-2010-4073, CVE-2010-4075, CVE-2010-4080, CVE-2010-4081, CVE-2010-4158, Low)
