Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5.

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 flaw was found in the Unidirectional Lightweight Encapsulation (ULE) implementation. A remote attacker could send a specially crafted ISO MPEG-2 Transport Stream (TS) frame to a target system, resulting in an infinite loop (denial of service). (CVE-2010-1086, Important)

* on AMD64 systems, it was discovered that the kernel did not ensure the ELF interpreter was available before making a call to the SET_PERSONALITY macro. A local attacker could use this flaw to cause a denial of service by running a 32-bit application that attempts to execute a 64-bit application. (CVE-2010-0307, Moderate)

* a flaw was found in the kernel connector implementation. A local, unprivileged user could trigger this flaw by sending an arbitrary number of notification requests using specially crafted netlink messages, resulting in a denial of service. (CVE-2010-0410, Moderate)

* a flaw was found in the Memory-mapped I/O (MMIO) instruction decoder in the Xen hypervisor implementation. An unprivileged guest user could use this flaw to trick the hypervisor into emulating a certain instruction, which could crash the guest (denial of service).
(CVE-2010-0730, Moderate)

* a divide-by-zero flaw was found in the azx_position_ok() function in the driver for Intel High Definition Audio, snd-hda-intel. A local, unprivileged user could trigger this flaw to cause a kernel crash (denial of service). (CVE-2010-1085, Moderate)

This update also fixes the following bugs :

* in some cases, booting a system with the 'iommu=on' kernel parameter resulted in a Xen hypervisor panic. (BZ#580199)

* the fnic driver flushed the Rx queue instead of the Tx queue after fabric login. This caused crashes in some cases. (BZ#580829)

* 'kernel unaligned access' warnings were logged to the dmesg log on some systems. (BZ#580832)

* the 'Northbridge Error, node 1, core: -1 K8 ECC error' error occurred on some systems using the amd64_edac driver. (BZ#580836)

* in rare circumstances, when using kdump and booting a kernel with 'crashkernel=128M@16M', the kdump kernel did not boot after a crash.
(BZ#580838)

* TLB page table entry flushing was done incorrectly on IBM System z, possibly causing crashes, subtle data inconsistency, or other issues.
(BZ#580839)

* iSCSI failover times were slower than in Red Hat Enterprise Linux 5.3. (BZ#580840)

* fixed floating point state corruption after signal. (BZ#580841)

* in certain circumstances, under heavy load, certain network interface cards using the bnx2 driver and configured to use MSI-X, could stop processing interrupts and then network connectivity would cease. (BZ#587799)

* cnic parts resets could cause a deadlock when the bnx2 device was enslaved in a bonding device and that device had an associated VLAN.
(BZ#581148)

* some BIOS implementations initialized interrupt remapping hardware in a way the Xen hypervisor implementation did not expect. This could have caused a system hang during boot. (BZ#581150)

* AMD Magny-Cours systems panicked when booting a 32-bit kernel.
(BZ#580846)

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.

From Red Hat Security Advisory 2010:0394 :

Updated kernel packages that fix multiple security issues, several bugs, and add three enhancements are now available for Red Hat Enterprise Linux 4.

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.

Security fixes :

* RHSA-2009:1024 introduced a flaw in the ptrace implementation on Itanium systems. ptrace_check_attach() was not called during certain ptrace() requests. Under certain circumstances, a local, unprivileged user could use this flaw to call ptrace() on a process they do not own, giving them control over that process. (CVE-2010-0729, Important)

* a flaw was found in the kernel's Unidirectional Lightweight Encapsulation (ULE) implementation. A remote attacker could send a specially crafted ISO MPEG-2 Transport Stream (TS) frame to a target system, resulting in a denial of service. (CVE-2010-1086, Important)

* a use-after-free flaw was found in tcp_rcv_state_process() in the kernel's TCP/IP protocol suite implementation. If a system using IPv6 had the IPV6_RECVPKTINFO option set on a listening socket, a remote attacker could send an IPv6 packet to that system, causing a kernel panic. (CVE-2010-1188, Important)

* a divide-by-zero flaw was found in azx_position_ok() in the Intel High Definition Audio driver, snd-hda-intel. A local, unprivileged user could trigger this flaw to cause a denial of service.
(CVE-2010-1085, Moderate)

* an information leak flaw was found in the kernel's USB implementation. Certain USB errors could result in an uninitialized kernel buffer being sent to user-space. An attacker with physical access to a target system could use this flaw to cause an information leak. (CVE-2010-1083, Low)

Red Hat would like to thank Ang Way Chuang for reporting CVE-2010-1086.

Bug fixes :

* a regression prevented the Broadcom BCM5761 network device from working when in the first (top) PCI-E slot of Hewlett-Packard (HP) Z600 systems. Note: The card worked in the 2nd or 3rd PCI-E slot.
(BZ#567205)

* the Xen hypervisor supports 168 GB of RAM for 32-bit guests. The physical address range was set incorrectly, however, causing 32-bit, para-virtualized Red Hat Enterprise Linux 4.8 guests to crash when launched on AMD64 or Intel 64 hosts that have more than 64 GB of RAM.
(BZ#574392)

* RHSA-2009:1024 introduced a regression, causing diskdump to fail on systems with certain adapters using the qla2xxx driver. (BZ#577234)

* a race condition caused TX to stop in a guest using the virtio_net driver. (BZ#580089)

* on some systems, using the 'arp_validate=3' bonding option caused both links to show as 'down' even though the arp_target was responding to ARP requests sent by the bonding driver. (BZ#580842)

* in some circumstances, when a Red Hat Enterprise Linux client connected to a re-booted Windows-based NFS server, server-side filehandle-to-inode mapping changes caused a kernel panic.
'bad_inode_ops' handling was changed to prevent this. Note:
filehandle-to-inode mapping changes may still cause errors, but not panics. (BZ#582908)

* when installing a Red Hat Enterprise Linux 4 guest via PXE, hard-coded fixed-size scatterlists could conflict with host requests, causing the guest's kernel to panic. With this update, dynamically allocated scatterlists are used, resolving this issue. (BZ#582911)

Enhancements :

* kernel support for connlimit. Note: iptables errata update RHBA-2010:0395 is also required for connlimit to work correctly.
(BZ#563223)

* support for the Intel architectural performance monitoring subsystem (arch_perfmon). On supported CPUs, arch_perfmon offers means to mark performance events and options for configuring and counting these events. (BZ#582913)

* kernel support for OProfile sampling of Intel microarchitecture (Nehalem) CPUs. This update alone does not address OProfile support for such CPUs. A future oprofile package update will allow OProfile to work on Intel Nehalem CPUs. (BZ#582241)

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

  - a regression prevented the Broadcom BCM5761 network     device from working when in the first (top) PCI-E slot     of Hewlett-Packard (HP) Z600 systems. Note: The card     worked in the 2nd or 3rd PCI-E slot. (BZ#567205)

  - the Xen hypervisor supports 168 GB of RAM for 32-bit     guests. The physical address range was set incorrectly,     however, causing 32-bit, para-virtualized Scientific     Linux 4.8 guests to crash when launched on AMD64 or     Intel 64 hosts that have more than 64 GB of RAM.
    (BZ#574392)

  - Kernel update 2.6.9-89.EL introduced a regression,     causing diskdump to fail on systems with certain     adapters using the qla2xxx driver. (BZ#577234)

  - a race condition caused TX to stop in a guest using the     virtio_net driver. (BZ#580089)

  - on some systems, using the 'arp_validate=3' bonding     option caused both links to show as 'down' even though     the arp_target was responding to ARP requests sent by     the bonding driver. (BZ#580842)

  - in some circumstances, when a Scientific Linux client     connected to a re-booted Windows-based NFS server,     server-side filehandle-to-inode mapping changes caused a     kernel panic. 'bad_inode_ops' handling was changed to     prevent this. Note: filehandle-to-inode mapping changes     may still cause errors, but not panics. (BZ#582908)

  - when installing a Scientific Linux 4 guest via PXE,     hard-coded fixed-size scatterlists could conflict with     host requests, causing the guest's kernel to panic. With     this update, dynamically allocated scatterlists are     used, resolving this issue. (BZ#582911)

Enhancements :

  - kernel support for connlimit. Note: iptables errata     update RHBA-2010:0395 is also required for connlimit to     work correctly. (BZ#563223)

  - support for the Intel architectural performance     monitoring subsystem (arch_perfmon). On supported CPUs,     arch_perfmon offers means to mark performance events and     options for configuring and counting these events.
    (BZ#582913)

  - kernel support for OProfile sampling of Intel     microarchitecture (Nehalem) CPUs. This update alone does     not address OProfile support for such CPUs. A future     oprofile package update will allow OProfile to work on     Intel Nehalem CPUs. (BZ#582241)

The system must be rebooted for this update to take effect.

a. vCenter Server and vCenter Update Manager update Microsoft    SQL Server 2005 Express Edition to Service Pack 3

   Microsoft SQL Server 2005 Express Edition (SQL Express)    distributed with vCenter Server 4.1 Update 1 and vCenter Update    Manager 4.1 Update 1 is upgraded from  SQL Express Service Pack 2    to SQL Express Service Pack 3, to address multiple security    issues that exist in the earlier releases of Microsoft SQL Express.

   Customers using other database solutions need not update for    these issues.

b. vCenter Apache Tomcat Management Application Credential Disclosure

   The Apache Tomcat Manager application configuration file contains    logon credentials that can be read by unprivileged local users.

   The issue is resolved by removing the Manager application in    vCenter 4.1 Update 1.

   If vCenter 4.1 is updated to vCenter 4.1 Update 1 the logon    credentials are not present in the configuration file after the    update.

   VMware would like to thank Claudio Criscione of Secure Networking    for reporting this issue to us.
