Updated kernel-rt packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise MRG 2.3.

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

This update fixes the following security issues :

* A heap-based buffer overflow flaw was found in the Linux kernel's iSCSI target subsystem. A remote attacker could use a specially crafted iSCSI request to cause a denial of service on a system or, potentially, escalate their privileges on that system. (CVE-2013-2850, Important)

* A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1 model-specific registers.
(CVE-2013-2146, Moderate)

* An invalid pointer dereference flaw was found in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system by using sendmsg() with an IPv6 socket connected to an IPv4 destination. (CVE-2013-2232, Moderate)

* Two flaws were found in the way the Linux kernel's TCP/IP protocol suite implementation handled IPv6 sockets that used the UDP_CORK option. A local, unprivileged user could use these flaws to cause a denial of service. (CVE-2013-4162, CVE-2013-4163, Moderate)

* A flaw was found in the Linux kernel's Chipidea USB driver. A local, unprivileged user could use this flaw to cause a denial of service.

* A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled duplicate cookies.
If a local user queried SCTP connection information at the same time a remote attacker has initialized a crafted SCTP connection to the system, it could trigger a NULL pointer dereference, causing the system to crash. (CVE-2013-2206, Important)

* It was found that the fix for CVE-2012-3552 released via RHSA-2012:1540 introduced an invalid free flaw in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to corrupt kernel memory via crafted sendmsg() calls, allowing them to cause a denial of service or, potentially, escalate their privileges on the system. (CVE-2013-2224, Important)

* An invalid pointer dereference flaw was found in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system by using sendmsg() with an IPv6 socket connected to an IPv4 destination. (CVE-2013-2232, Moderate)

* Information leak flaws in the Linux kernel could allow a privileged, local user to leak kernel memory to user-space. (CVE-2013-2164, CVE-2013-2147, CVE-2013-2234, CVE-2013-2237, Low)

This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Rebase to 3.9.8 now that 3.8 is no longer maintained.

Multiple vulnerabilities has been found and corrected in the Linux kernel :

net/ceph/auth_none.c in the Linux kernel through 3.10 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an auth_reply message that triggers an attempted build_request operation.
(CVE-2013-1059)

The HP Smart Array controller disk-array driver and Compaq SMART2 controller disk-array driver in the Linux kernel through 3.9.4 do not initialize certain data structures, which allows local users to obtain sensitive information from kernel memory via (1) a crafted IDAGETPCIINFO command for a /dev/ida device, related to the ida_locked_ioctl function in drivers/block/cpqarray.c or (2) a crafted CCISS_PASSTHRU32 command for a /dev/cciss device, related to the cciss_ioctl32_passthru function in drivers/block/cciss.c.
(CVE-2013-2147)

The fill_event_metadata function in fs/notify/fanotify/fanotify_user.c in the Linux kernel through 3.9.4 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory via a read operation on the fanotify descriptor. (CVE-2013-2148)

Format string vulnerability in the register_disk function in block/genhd.c in the Linux kernel through 3.9.4 allows local users to gain privileges by leveraging root access and writing format string specifiers to /sys/module/md_mod/parameters/new_array in order to create a crafted /dev/md device name. (CVE-2013-2851)

The mmc_ioctl_cdrom_read_data function in drivers/cdrom/cdrom.c in the Linux kernel through 3.10 allows local users to obtain sensitive information from kernel memory via a read operation on a malfunctioning CD-ROM drive. (CVE-2013-2164)

The key_notify_policy_flush function in net/key/af_key.c in the Linux kernel before 3.9 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory by reading a broadcast message from the notify_policy interface of an IPSec key_socket. (CVE-2013-2237)

The (1) key_notify_sa_flush and (2) key_notify_policy_flush functions in net/key/af_key.c in the Linux kernel before 3.10 do not initialize certain structure members, which allows local users to obtain sensitive information from kernel heap memory by reading a broadcast message from the notify interface of an IPSec key_socket.
(CVE-2013-2234)

The ip6_sk_dst_check function in net/ipv6/ip6_output.c in the Linux kernel before 3.10 allows local users to cause a denial of service (system crash) by using an AF_INET6 socket for a connection to an IPv4 interface. (CVE-2013-2232)

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. (CVE-2012-5517)

Format string vulnerability in the b43_request_firmware function in drivers/net/wireless/b43/main.c in the Broadcom B43 wireless driver in the Linux kernel through 3.9.4 allows local users to gain privileges by leveraging root access and including format string specifiers in an fwpostfix modprobe parameter, leading to improper construction of an error message. (CVE-2013-2852)

The ftrace implementation in the Linux kernel before 3.8.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for write access to the (1) set_ftrace_pid or (2) set_graph_function file, and then making an lseek system call. (CVE-2013-3301)

The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen for the Linux kernel 2.6.18 and 3.8 allows guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages.
NOTE: some of these details are obtained from third-party information.
(CVE-2013-0231)

The chase_port function in drivers/usb/serial/io_ti.c in the Linux kernel before 3.7.4 allows local users to cause a denial of service (NULL pointer dereference and system crash) via an attempted /dev/ttyUSB read or write operation on a disconnected Edgeport USB serial converter. (CVE-2013-1774)

Heap-based buffer overflow in the iscsi_add_notunderstood_response function in drivers/target/iscsi/iscsi_target_parameters.c in the iSCSI target subsystem in the Linux kernel through 3.9.4 allows remote attackers to cause a denial of service (memory corruption and OOPS) or possibly execute arbitrary code via a long key that is not properly handled during construction of an error-response packet.
(CVE-2013-2850)
