Title:	RedHat Security Advisory RHSA-2011:0927
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2011:0927. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * An integer overflow flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2010-4649, Important) * A race condition in the way new InfiniBand connections were set up could allow a remote user to cause a denial of service. (CVE-2011-0695, Important) * A flaw in the Stream Control Transmission Protocol (SCTP) implementation could allow a remote attacker to cause a denial of service if the sysctl net.sctp.addip_enable variable was turned on (it is off by default). (CVE-2011-1573, Important) * Flaws in the AGPGART driver implementation when handling certain IOCTL commands could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2011-1745, CVE-2011-2022, Important) * An integer overflow flaw in agp_allocate_memory() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2011-1746, Important) * A flaw allowed napi_reuse_skb() to be called on VLAN (virtual LAN) packets. An attacker on the local network could trigger this flaw by sending specially-crafted packets to a target system, possibly causing a denial of service. (CVE-2011-1576, Moderate) * An integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate) * A flaw in the way the Xen hypervisor implementation handled CPUID instruction emulation during virtual machine exits could allow an unprivileged guest user to crash a guest. This only affects systems that have an Intel x86 processor with the Intel VT-x extension enabled. (CVE-2011-1936, Moderate) * A flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service (infinite loop). (CVE-2011-2213, Moderate) * A missing initialization flaw in the XFS file system implementation could lead to an information leak. (CVE-2011-0711, Low) * A flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause an information leak. (CVE-2011-1044, Low) * A missing validation check was found in the signals implementation. A local, unprivileged user could use this flaw to send signals via the sigqueueinfo system call, with the si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. Note: This flaw does not allow existing permission checks to be bypassed signals can only be sent if your privileges allow you to already do so. (CVE-2011-1182, Low) * A heap overflow flaw in the EFI GUID Partition Table (GPT) implementation could allow a local attacker to cause a denial of service by mounting a disk containing specially-crafted partition tables. (CVE-2011-1776, Low) * Structure padding in two structures in the Bluetooth implementation was not initialized properly before being copied to user-space, possibly allowing local, unprivileged users to leak kernel stack memory to user-space. (CVE-2011-2492, Low) Red Hat would like to thank Jens Kuehnel for reporting CVE-2011-0695 Vasiliy Kulikov for reporting CVE-2011-1745, CVE-2011-2022, and CVE-2011-1746 Ryan Sweat for reporting CVE-2011-1576 Robert Swiecki for reporting CVE-2011-1593 Dan Rosenberg for reporting CVE-2011-2213 and CVE-2011-0711 Julien Tinnes of the Google Security Team for reporting CVE-2011-1182 Timo Warns for reporting CVE-2011-1776 and Marek Kroemeke and Filip Palian for reporting CVE-2011-2492. Bug fix documentation will be available shortly from the Technical Notes document linked to in the References. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2011-0927.html Risk factor : High CVSS Score: 6.9
