The remote OracleVM system is missing necessary patches to address critical security updates :

CVE-2008-4307 Race condition in the do_setlk function in fs/nfs/file.c in the Linux kernel before 2.6.26 allows local users to cause a denial of service (crash) via vectors resulting in an interrupted RPC call that leads to a stray FL_POSIX lock, related to improper handling of a race between fcntl and close in the EINTR case.

CVE-2009-1337 The exit_notify function in kernel/exit.c in the Linux kernel before 2.6.30-rc1 does not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application.

CVE-2009-0834 The audit_syscall_entry function in the Linux kernel 2.6.28.7 and earlier on the x86_64 platform does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls, a related issue to CVE-2009-0342 and CVE-2009-0343.

CVE-2009-1336 fs/nfs/client.c in the Linux kernel before 2.6.23 does not properly initialize a certain structure member that stores the maximum NFS filename length, which allows local users to cause a denial of service (OOPS) via a long filename, related to the encode_lookup function.

From Red Hat Security Advisory 2009:0473 :

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

This update has been rated as having important security impact by the Red Hat Security Response Team.

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

This update fixes the following security issues :

* a logic error was found in the do_setlk() function of the Linux kernel Network File System (NFS) implementation. If a signal interrupted a lock request, the local POSIX lock was incorrectly created. This could cause a denial of service on the NFS server if a file descriptor was closed before its corresponding lock request returned. (CVE-2008-4307, Important)

* a deficiency was found in the Linux kernel system call auditing implementation on 64-bit systems. This could allow a local, unprivileged user to circumvent a system call audit configuration, if that configuration filtered based on the 'syscall' number or arguments. (CVE-2009-0834, Important)

* the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)

* a flaw was found in the ecryptfs_write_metadata_to_contents() function of the Linux kernel eCryptfs implementation. On systems with a 4096 byte page-size, this flaw may have caused 4096 bytes of uninitialized kernel memory to be written into the eCryptfs file headers, leading to an information leak. Note: Encrypted files created on systems running the vulnerable version of eCryptfs may contain leaked data in the eCryptfs file headers. This update does not remove any leaked data. Refer to the Knowledgebase article in the References section for further information. (CVE-2009-0787, Moderate)

* the Linux kernel implementation of the Network File System (NFS) did not properly initialize the file name limit in the nfs_server data structure. This flaw could possibly lead to a denial of service on a client mounting an NFS share. (CVE-2009-1336, Moderate)

This update also fixes the following bugs :

* the enic driver (Cisco 10G Ethernet) did not operate under virtualization. (BZ#472474)

* network interfaces using the IBM eHEA Ethernet device driver could not be successfully configured under low-memory conditions.
(BZ#487035)

* bonding with the 'arp_validate=3' option may have prevented fail overs. (BZ#488064)

* when running under virtualization, the acpi-cpufreq module wrote 'Domain attempted WRMSR' errors to the dmesg log. (BZ#488928)

* NFS clients may have experienced deadlocks during unmount.
(BZ#488929)

* the ixgbe driver double counted the number of received bytes and packets. (BZ#489459)

* the Wacom Intuos3 Lens Cursor device did not work correctly with the Wacom Intuos3 12x12 tablet. (BZ#489460)

* on the Itanium(r) architecture, nanosleep() caused commands which used it, such as sleep and usleep, to sleep for one second more than expected. (BZ#490434)

* a panic and corruption of slab cache data structures occurred on 64-bit PowerPC systems when clvmd was running. (BZ#491677)

* the NONSTOP_TSC feature did not perform correctly on the Intel(r) microarchitecture (Nehalem) when running in 32-bit mode. (BZ#493356)

* keyboards may not have functioned on IBM eServer System p machines after a certain point during installation or afterward. (BZ#494293)

* using Device Mapper Multipathing with the qla2xxx driver resulted in frequent path failures. (BZ#495635)

* if the hypervisor was booted with the dom0_max_vcpus parameter set to less than the actual number of CPUs in the system, and the cpuspeed service was started, the hypervisor could crash. (BZ#495931)

* using Openswan to provide an IPsec virtual private network eventually resulted in a CPU soft lockup and a system crash.
(BZ#496044)

* it was possible for posix_locks_deadlock() to enter an infinite loop (under the BKL), causing a system hang. (BZ#496842)

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 2009:0459 :

Updated kernel packages that fix several security issues and various bugs are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

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

Security fixes :

If a signal interrupted a lock request, the local POSIX lock was incorrectly created. This could cause a denial of service on the NFS server if a file descriptor was closed before its corresponding lock request returned. (CVE-2008-4307, Important)

* Chris Evans reported a deficiency in the Linux kernel signals implementation. The clone() system call permits the caller to indicate the signal it wants to receive when its child exits. When clone() is called with the CLONE_PARENT flag, it permits the caller to clone a new child that shares the same parent as itself, enabling the indicated signal to be sent to the caller's parent (instead of the caller), even if the caller's parent has different real and effective user IDs. This could lead to a denial of service of the parent.
(CVE-2009-0028, Moderate)

* the sock_getsockopt() function in the Linux kernel did not properly initialize a data structure that can be directly returned to user-space when the getsockopt() function is called with SO_BSDCOMPAT optname set. This flaw could possibly lead to memory disclosure.
(CVE-2009-0676, Moderate)

Bug fixes :

* a kernel crash may have occurred for Red Hat Enterprise Linux 4.7 guests if their guest configuration file specified 'vif = [ 'type=ioemu' ]'. This crash only occurred when starting guests via the 'xm create' command. (BZ#477146)

* a bug in IO-APIC NMI watchdog may have prevented Red Hat Enterprise Linux 4.7 from being installed on HP ProLiant DL580 G5 systems. Hangs during installation and 'NMI received for unknown reason [xx]' errors may have occurred. (BZ#479184)

* a kernel deadlock on some systems when using netdump through a network interface that uses the igb driver. (BZ#480579)

* a possible kernel hang in sys_ptrace() on the Itanium(r) architecture, possibly triggered by tracing a threaded process with strace. (BZ#484904)

* the RHSA-2008:0665 errata only fixed the known problem with the LSI Logic LSI53C1030 Ultra320 SCSI controller, for tape devices. Read commands sent to tape devices may have received incorrect data. This issue may have led to data corruption. This update includes a fix for all types of devices. (BZ#487399)

* a missing memory barrier caused a race condition in the AIO subsystem between the read_events() and aio_complete() functions. This may have caused a thread in read_events() to sleep indefinitely, possibly causing an application hang. (BZ#489935)

* due to a lack of synchronization in the NFS client code, modifications to some pages (for files on an NFS mounted file system) made through a region of memory mapped by mmap() may be lost if the NFS client invalidates its page cache for particular files.
(BZ#490119)

* a NULL pointer dereference in the megaraid_mbox driver caused a system crash on some systems. (BZ#493420)

* the ext3_symlink() function in the ext3 file system code used an illegal __GFP_FS allocation inside some transactions. This may have resulted in a kernel panic and 'Assertion failure' errors. (BZ#493422)

* do_machine_check() cleared all Machine Check Exception (MCE) status registers, preventing the BIOS from using them to determine the cause of certain panics and errors. (BZ#494915)

* a bug prevented NMI watchdog from initializing on HP ProLiant DL580 G5 systems. (BZ#497330)

This update contains backported patches to fix these issues. The system must be rebooted for this update to take effect.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5.2 Extended Update Support.

This update has been rated as having important security impact by the Red Hat Security Response Team.

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 IPv6 Extension Header (EH) handling implementation in the Linux kernel. The skb->dst data structure was not properly validated in the ipv6_hop_jumbo() function. This could possibly lead to a remote denial of service. (CVE-2007-4567, Important)

* the possibility of a timeout value overflow was found in the Linux kernel high-resolution timers functionality, hrtimers. This could allow a local, unprivileged user to execute arbitrary code, or cause a denial of service (kernel panic). (CVE-2007-5966, Important)

* memory leaks were found on some error paths in the icmp_send() function in the Linux kernel. This could, potentially, cause the network connectivity to cease. (CVE-2009-0778, Important)

* a deficiency was found in the Linux kernel system call auditing implementation on 64-bit systems. This could allow a local, unprivileged user to circumvent a system call audit configuration, if that configuration filtered based on the 'syscall' number or arguments. (CVE-2009-0834, Important)

* a flaw was found in the Intel PRO/1000 Linux driver (e1000) in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important)

* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.
(CVE-2009-1895, Important)

* a flaw was found in each of the following Intel PRO/1000 Linux drivers in the Linux kernel: e1000 and e1000e. A remote attacker using packets larger than the MTU could bypass the existing fragment check, resulting in partial, invalid frames being passed to the network stack. These flaws could also possibly be used to trigger a remote denial of service. (CVE-2009-4536, CVE-2009-4538, Important)

* a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. Receiving overly-long frames with a certain revision of the network cards supported by this driver could possibly result in a remote denial of service. (CVE-2009-4537, Important)

Note: This update also fixes several bugs. Documentation for these bug fixes will be available shortly from www.redhat.com/docs/en-US/errata/RHSA-2010-0079/Kernel_Security_Update / index.html

The Linux kernel on SUSE Linux Enterprise 10 Service Pack 2 was updated to fix various security issues and several bugs.

The following security issues were fixed: CVE-2009-0834: The audit_syscall_entry function in the Linux kernel on the x86_64 platform did not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls.

  - nfsd in the Linux kernel did not drop the CAP_MKNOD     capability before handling a user request in a thread,     which allows local users to create device nodes, as     demonstrated on a filesystem that has been exported with     the root_squash option. (CVE-2009-1072)

  - The __secure_computing function in kernel/seccomp.c in     the seccomp subsystem in the Linux kernel on the x86_64     platform, when CONFIG_SECCOMP is enabled, does not     properly handle (1) a 32-bit process making a 64-bit     syscall or (2) a 64-bit process making a 32-bit syscall,     which allows local users to bypass intended access     restrictions via crafted syscalls that are     misinterpreted as (a) stat or (b) chmod. (CVE-2009-0835)

  - Buffer overflow in fs/cifs/connect.c in CIFS in the     Linux kernel 2.6.29 and earlier allows remote attackers     to cause a denial of service (crash) or potential code     execution via a long nativeFileSystem field in a Tree     Connect response to an SMB mount request.
    (CVE-2009-1439)

This requires that kernel can be made to mount a 'cifs' filesystem from a malicious CIFS server.

  - The exit_notify function in kernel/exit.c in the Linux     kernel did not restrict exit signals when the CAP_KILL     capability is held, which allows local users to send an     arbitrary signal to a process by running a program that     modifies the exit_signal field and then uses an exec     system call to launch a setuid application.
    (CVE-2009-1337)

  - The shm_get_stat function in ipc/shm.c in the shm     subsystem in the Linux kernel, when CONFIG_SHMEM is     disabled, misinterprets the data type of an inode, which     allows local users to cause a denial of service (system     hang) via an SHM_INFO shmctl call, as demonstrated by     running the ipcs program. (SUSE is enabling     CONFIG_SHMEM, so is by default not affected, the fix is     just for completeness). (CVE-2009-0859)

The GCC option -fwrapv has been added to compilation to work around potentially removing integer overflow checks.

  - Integer overflow in rose_sendmsg (sys/net/af_rose.c) in     the Linux kernel might allow attackers to obtain     sensitive information via a large length value, which     causes 'garbage' memory to be sent. (CVE-2009-1265)

Also a number of bugs were fixed, for details please see the RPM changelog.

 f. Updated Service Console package python

  Service Console package Python update to version 2.4.3-24.el5.

  When the assert() system call was disabled, an input sanitization   flaw was revealed in the Python string object implementation that   led to a buffer overflow. The missing check for negative size values   meant the Python memory allocator could allocate less memory than   expected. This could result in arbitrary code execution with the   Python interpreter's privileges.

  Multiple buffer and integer overflow flaws were found in the Python   Unicode string processing and in the Python Unicode and string   object implementations. An attacker could use these flaws to cause   a denial of service.

  Multiple integer overflow flaws were found in the Python imageop   module. If a Python application used the imageop module to   process untrusted images, it could cause the application to   disclose sensitive information, crash or, potentially, execute   arbitrary code with the Python interpreter's privileges.

  Multiple integer underflow and overflow flaws were found in the   Python snprintf() wrapper implementation. An attacker could use   these flaws to cause a denial of service (memory corruption).

  Multiple integer overflow flaws were found in various Python   modules. An attacker could use these flaws to cause a denial of   service.

  An integer signedness error, leading to a buffer overflow, was   found in the Python zlib extension module. If a Python application   requested the negative byte count be flushed for a decompression   stream, it could cause the application to crash or, potentially,   execute arbitrary code with the Python interpreter's privileges.

  A flaw was discovered in the strxfrm() function of the Python   locale module. Strings generated by this function were not properly   NULL-terminated, which could possibly cause disclosure of data   stored in the memory of a Python application using this function.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2007-2052 CVE-2007-4965 CVE-2008-1721   CVE-2008-1887 CVE-2008-2315 CVE-2008-3142 CVE-2008-3143   CVE-2008-3144 CVE-2008-4864 CVE-2008-5031 to these issues.

 g. Updated Service Console package bind

  Service Console package bind updated to version 9.3.6-4.P1.el5

  The Berkeley Internet Name Domain (BIND) is an implementation of the   Domain Name System (DNS) protocols. BIND includes a DNS server   (named); a resolver library (routines for applications to use when   interfacing with DNS); and tools for verifying that the DNS server   is operating correctly.

  A flaw was found in the way BIND handles dynamic update message   packets containing the 'ANY' record type. A remote attacker could   use this flaw to send a specially crafted dynamic update packet   that could cause named to exit with an assertion failure.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-0696 to this issue.

 h. Updated Service Console package libxml2

  Service Console package libxml2 updated to version 2.6.26-2.1.2.8.

  libxml is a library for parsing and manipulating XML files. A   Document Type Definition (DTD) defines the legal syntax (and also   which elements can be used) for certain types of files, such as XML   files.

  A stack overflow flaw was found in the way libxml processes the   root XML document element definition in a DTD. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  Multiple use-after-free flaws were found in the way libxml parses   the Notation and Enumeration attribute types. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2009-2414 and CVE-2009-2416 to these   issues.

 i. Updated Service Console package curl

  Service Console package curl updated to version 7.15.5-2.1.el5_3.5

  A cURL is affected by the previously published 'null prefix attack',   caused by incorrect handling of NULL characters in X.509   certificates. If an attacker is able to get a carefully-crafted   certificate signed by a trusted Certificate Authority, the attacker   could use the certificate during a man-in-the-middle attack and   potentially confuse cURL into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2417 to this issue

 j. Updated Service Console package gnutls

  Service Console package gnutil updated to version 1.4.1-3.el5_3.5

  A flaw was discovered in the way GnuTLS handles NULL characters in   certain fields of X.509 certificates. If an attacker is able to get   a carefully-crafted certificate signed by a Certificate Authority   trusted by an application using GnuTLS, the attacker could use the   certificate during a man-in-the-middle attack and potentially   confuse the application into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2730 to this issue

This kernel update for openSUSE 11.0 fixes some bugs and several security problems.

The following security issues are fixed: A local denial of service problem in the splice(2) system call.

CVE-2009-1630: The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.

CVE-2009-0834: The audit_syscall_entry function in the Linux kernel on the x86_64 platform did not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls.

CVE-2009-1072: nfsd in the Linux kernel did not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.

CVE-2009-0835 The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod.

CVE-2009-1439: Buffer overflow in fs/cifs/connect.c in CIFS in the Linux kernel 2.6.29 and earlier allows remote attackers to cause a denial of service (crash) or potential code execution via a long nativeFileSystem field in a Tree Connect response to an SMB mount request.

This requires that kernel can be made to mount a 'cifs' filesystem from a malicious CIFS server.

CVE-2009-1337: The exit_notify function in kernel/exit.c in the Linux kernel did not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application.

CVE-2009-0859: The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program. (SUSE is enabling CONFIG_SHMEM, so is by default not affected, the fix is just for completeness).

CVE-2009-1242: The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel on the i386 platform allows guest OS users to cause a denial of service (OOPS) by setting the EFER_LME (aka 'Long mode enable') bit in the Extended Feature Enable Register (EFER) model-specific register, which is specific to the x86_64 platform.

CVE-2009-1265: Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel might allow attackers to obtain sensitive information via a large length value, which causes 'garbage' memory to be sent.

CVE-2009-0028: The clone system call in the Linux kernel allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit.

CVE-2009-0675: The skfp_ioctl function in drivers/net/skfp/skfddi.c in the Linux kernel permits SKFP_CLR_STATS requests only when the CAP_NET_ADMIN capability is absent, instead of when this capability is present, which allows local users to reset the driver statistics, related to an 'inverted logic' issue.

CVE-2009-0676: The sock_getsockopt function in net/core/sock.c in the Linux kernel does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request.

CVE-2009-0322: drivers/firmware/dell_rbu.c in the Linux kernel allows local users to cause a denial of service (system crash) via a read system call that specifies zero bytes from the (1) image_type or (2) packet_size file in /sys/devices/platform/dell_rbu/.

CVE-2009-0269: fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index.

CVE-2009-0065: Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID.

Some other non-security bugs were fixed, please see the RPM changelog.

This kernel update for openSUSE 10.3 fixes some bugs and several security problems.

CVE-2008-4554: The do_splice_from function in fs/splice.c in the Linux kernel does not reject file descriptors that have the O_APPEND flag set, which allows local users to bypass append mode and make arbitrary changes to other locations in the file.

Some other non-security bugs were fixed, please see the RPM changelog.

Updated kernel packages that fix several security issues and various bugs are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

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

Security fixes :

* a logic error was found in the do_setlk() function of the Linux kernel Network File System (NFS) implementation. If a signal interrupted a lock request, the local POSIX lock was incorrectly created. This could cause a denial of service on the NFS server if a file descriptor was closed before its corresponding lock request returned. (CVE-2008-4307, Important)

* a deficiency was found in the Linux kernel system call auditing implementation on 64-bit systems. This could allow a local, unprivileged user to circumvent a system call audit configuration, if that configuration filtered based on the 'syscall' number or arguments. (CVE-2009-0834, Important)

* Chris Evans reported a deficiency in the Linux kernel signals implementation. The clone() system call permits the caller to indicate the signal it wants to receive when its child exits. When clone() is called with the CLONE_PARENT flag, it permits the caller to clone a new child that shares the same parent as itself, enabling the indicated signal to be sent to the caller's parent (instead of the caller), even if the caller's parent has different real and effective user IDs. This could lead to a denial of service of the parent.
(CVE-2009-0028, Moderate)

* the sock_getsockopt() function in the Linux kernel did not properly initialize a data structure that can be directly returned to user-space when the getsockopt() function is called with SO_BSDCOMPAT optname set. This flaw could possibly lead to memory disclosure.
(CVE-2009-0676, Moderate)

Bug fixes :

* a kernel crash may have occurred for Red Hat Enterprise Linux 4.7 guests if their guest configuration file specified 'vif = [ 'type=ioemu' ]'. This crash only occurred when starting guests via the 'xm create' command. (BZ#477146)

* a bug in IO-APIC NMI watchdog may have prevented Red Hat Enterprise Linux 4.7 from being installed on HP ProLiant DL580 G5 systems. Hangs during installation and 'NMI received for unknown reason [xx]' errors may have occurred. (BZ#479184)

* a kernel deadlock on some systems when using netdump through a network interface that uses the igb driver. (BZ#480579)

* a possible kernel hang in sys_ptrace() on the Itanium(r) architecture, possibly triggered by tracing a threaded process with strace. (BZ#484904)

* the RHSA-2008:0665 errata only fixed the known problem with the LSI Logic LSI53C1030 Ultra320 SCSI controller, for tape devices. Read commands sent to tape devices may have received incorrect data. This issue may have led to data corruption. This update includes a fix for all types of devices. (BZ#487399)

* a missing memory barrier caused a race condition in the AIO subsystem between the read_events() and aio_complete() functions. This may have caused a thread in read_events() to sleep indefinitely, possibly causing an application hang. (BZ#489935)

* due to a lack of synchronization in the NFS client code, modifications to some pages (for files on an NFS mounted file system) made through a region of memory mapped by mmap() may be lost if the NFS client invalidates its page cache for particular files.
(BZ#490119)

* a NULL pointer dereference in the megaraid_mbox driver caused a system crash on some systems. (BZ#493420)

* the ext3_symlink() function in the ext3 file system code used an illegal __GFP_FS allocation inside some transactions. This may have resulted in a kernel panic and 'Assertion failure' errors. (BZ#493422)

* do_machine_check() cleared all Machine Check Exception (MCE) status registers, preventing the BIOS from using them to determine the cause of certain panics and errors. (BZ#494915)

* a bug prevented NMI watchdog from initializing on HP ProLiant DL580 G5 systems. (BZ#497330)

This update contains backported patches to fix these issues. The system must be rebooted for this update to take effect.

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel :

The clone system call in the Linux kernel 2.6.28 and earlier allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit.
(CVE-2009-0028)

fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel before 2.6.28.1 allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index. (CVE-2009-0269)

The audit_syscall_entry function in the Linux kernel 2.6.28.7 and earlier on the x86_64 platform does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls, a related issue to CVE-2009-0342 and CVE-2009-0343. (CVE-2009-0834)

The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel 2.6.28.7 and earlier on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod, a related issue to CVE-2009-0342 and CVE-2009-0343. (CVE-2009-0835)

The selinux_ip_postroute_iptables_compat function in security/selinux/hooks.c in the SELinux subsystem in the Linux kernel before 2.6.27.22, and 2.6.28.x before 2.6.28.10, when compat_net is enabled, omits calls to avc_has_perm for the (1) node and (2) port, which allows local users to bypass intended restrictions on network traffic. NOTE: this was incorrectly reported as an issue fixed in 2.6.27.21. (CVE-2009-1184)

Additionally, along with other things, this kernel update adds support for D-Link DWM 652 3.5G, some Intel gigabit network chipsets, Avermedia PCI pure analog (M135A), fixes a bug causing SQLite performance regression, and has some updated ALSA drivers. Check the package changelog for details.
