The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2011-489:04 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-2011-1593     Multiple integer overflows in the next_pidmap function in kernel/pid.c in     the Linux kernel before 2.6.38.4 allow local users to cause a denial of service     (system crash) via a crafted (1) getdents or (2) readdir system call.
    CVE-2011-1898     Xen 4.1 before 4.1.1 and 4.0 before 4.0.2, when using PCI passthrough on Intel VT-d chipsets that do not     have interrupt remapping, allows guest OS users to gain host OS privileges by using DMA to generate MSI     interrupts by writing to the interrupt injection registers.
    CVE-2011-2492     The bluetooth subsystem in the Linux kernel before 3.0-rc4 does not properly initialize certain data     structures, which allows local users to obtain potentially sensitive information from kernel memory via a     crafted getsockopt system call, related to (1) the l2cap_sock_getsockopt_old function in     net/bluetooth/l2cap_sock.c and (2) the rfcomm_sock_getsockopt_old function in net/bluetooth/rfcomm/sock.c.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2011-264:04 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 '0' 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 '0' 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 '0' 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.

This kernel update for the SUSE Linux Enterprise 10 SP4 kernel fixes several security issues and bugs.

The following security issues were fixed :

  - The dccp_rcv_state_process function in net/dccp/input.c     in the Datagram Congestion Control Protocol (DCCP)     implementation in the Linux kernel did not properly     handle packets for a CLOSED endpoint, which allowed     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-2011-1093)

  - The add_del_listener function in kernel/taskstats.c in     the Linux kernel did not prevent multiple registrations     of exit handlers, which allowed local users to cause a     denial of service (memory and CPU consumption), and     bypass the OOM Killer, via a crafted application.
    (CVE-2011-2484)

  - Integer overflow in the agp_generic_insert_memory     function in drivers/char/agp/generic.c in the Linux     kernel allowed local users to gain privileges or cause a     denial of service (system crash) via a crafted     AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745)

  - Multiple integer overflows in the (1)     agp_allocate_memory and (2) agp_create_user_memory     functions in drivers/char/agp/generic.c in the Linux     kernel allowed local users to trigger buffer overflows,     and consequently cause a denial of service (system     crash) or possibly have unspecified other impact, via     vectors related to calls that specify a large number of     memory pages. (CVE-2011-1746)

  - The agp_generic_remove_memory function in     drivers/char/agp/generic.c in the Linux kernel before     2.6.38.5 did not validate a certain start parameter,     which allowed local users to gain privileges or cause a     denial of service (system crash) via a crafted     AGPIOC_UNBIND agp_ioctl ioctl call, a different     vulnerability than CVE-2011-1745. (CVE-2011-2022)

  - When using a setuid root mount.cifs, local users could     hijack password protected mounted CIFS shares of other     local users. (CVE-2011-1585)

  - The do_task_stat function in fs/proc/array.c in the     Linux kernel did not perform an expected uid check,     which made 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-2011-0726)

  - The normal mmap paths all avoid creating a mapping where     the pgoff inside the mapping could wrap around due to     overflow. However, an expanding mremap() can take such a     non-wrapping mapping and make it bigger and cause a     wrapping condition. (CVE-2011-2496)

  - A local unprivileged user able to access a NFS     filesystem could use file locking to deadlock parts of     an nfs server under some circumstance. (CVE-2011-2491)

  - The code for evaluating LDM partitions (in     fs/partitions/ldm.c) contained bugs that could crash the     kernel for certain corrupted LDM partitions.
    (CVE-2011-1017 / CVE-2011-2182)

  - Multiple integer overflows in the next_pidmap function     in kernel/pid.c in the Linux kernel allowed local users     to cause a denial of service (system crash) via a     crafted (1) getdents or (2) readdir system call.
    (CVE-2011-1593)

  - Integer overflow in the _ctl_do_mpt_command function in     drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel     might have allowed 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-2011-1494)

  - drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel     did not validate (1) length and (2) offset values before     performing memory copy operations, which might have     allowed 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-2011-1495)
