  - cURL/libcURL
  - ISC BIND
  - Libxml2
  - Linux kernel
  - Linux kernel 64-bit
  - Linux kernel Common Internet File System
  - Linux kernel eCryptfs
  - NTP
  - Python
  - Java Runtime Environment (JRE)
  - Java SE Development Kit (JDK)
  - Java SE Abstract Window Toolkit (AWT)
  - Java SE Plugin

  - Java SE Swing
  - Java SE Web Start

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.

Updated kernel packages that fix two security issues and two bugs are now available for Red Hat Enterprise Linux 4.7 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 includes backported fixes for two approved security issues. These issues only affected users of Red Hat Enterprise Linux 4.7 Extended Update Support, as they have already been addressed for users of Red Hat Enterprise Linux 4 in the 4.8 update, RHSA-2009:1024.

* 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)

* the Linux kernel implementation of the Network File System (NFS) version 4 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 NFSv4 share. (CVE-2009-1336, Moderate)

This update fixes the following bugs :

* on IBM System z systems, if the cio driver was used for DASD devices, and the last path to a DASD device was varied off, it was still possible to attempt read and write operations to that device, resulting in errors. In this update, path verification is used in this situation, which resolves this issue. Also, a bug may have caused errors when subchannels were unregistered. (BZ#437486)

* a bug prevented the Broadcom NetXtreme II 57710 network device from working correctly on some Dell PowerEdge R805 systems. This device was correctly shown in 'lspci' output, but 'ifup' failed and an IP address was not assigned. In this update, the device works correctly on Dell PowerEdge R805 systems. (BZ#491752)

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

These updated packages fix the following security issues :

  - 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)

  - 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)

  - a flaw was found in the Intel PRO/1000 network driver 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. (CVE-2009-1385, Important)

  - the Linux kernel Network File System daemon (nfsd)     implementation did not drop the CAP_MKNOD capability     when handling requests from local, unprivileged users.
    This flaw could possibly lead to an information leak or     privilege escalation. (CVE-2009-1072, Moderate)

  - Frank Filz reported the NFSv4 client was missing a file     permission check for the execute bit in some situations.
    This could allow local, unprivileged users to run     non-executable files on NFSv4 mounted file systems.
    (CVE-2009-1630, Moderate)

  - a missing check was found in the hypervisor_callback()     function in the Linux kernel provided by the kernel-xen     package. This could cause a denial of service of a     32-bit guest if an application running in that guest     accesses a certain memory location in the kernel.
    (CVE-2009-1758, Moderate)

  - a flaw was found in the AGPGART driver. The     agp_generic_alloc_page() and agp_generic_alloc_pages()     functions did not zero out the memory pages they     allocate, which may later be available to user-space     processes. This flaw could possibly lead to an     information leak. (CVE-2009-1192, Low)

These updated packages also fix the following bugs :

  - '/proc/[pid]/maps' and '/proc/[pid]/smaps' can only be     read by processes able to use the ptrace() call on a     given process; however, certain information from     '/proc/[pid]/stat' and '/proc/[pid]/wchan' could be used     to reconstruct memory maps, making it possible to bypass     the Address Space Layout Randomization (ASLR) security     feature. This update addresses this issue. (BZ#499549)

  - in some situations, the link count was not decreased     when renaming unused files on NFS mounted file systems.
    This may have resulted in poor performance. With this     update, the link count is decreased in these situations,     the same as is done for other file operations, such as     unlink and rmdir. (BZ#501802)

  - tcp_ack() cleared the probes_out variable even if there     were outstanding packets. When low TCP keepalive     intervals were used, this bug may have caused problems,     such as connections terminating, when using remote tools     such as rsh and rlogin. (BZ#501754)

  - off-by-one errors in the time normalization code could     have caused clock_gettime() to return one billion     nanoseconds, rather than adding an extra second. This     bug could have caused the name service cache daemon     (nscd) to consume excessive CPU resources. (BZ#501800)

  - a system panic could occur when one thread read     '/proc/bus/input/devices' while another was removing a     device. With this update, a mutex has been added to     protect the input_dev_list and input_handler_list     variables, which resolves this issue. (BZ#501804)

  - using netdump may have caused a kernel deadlock on some     systems. (BZ#504565)

  - the file system mask, which lists capabilities for users     with a file system user ID (fsuid) of 0, was missing the     CAP_MKNOD and CAP_LINUX_IMMUTABLE capabilities. This     could, potentially, allow users with an fsuid other than     0 to perform actions on some file system types that     would otherwise be prevented. This update adds these     capabilities. (BZ#497269)

Kernel Feature Support :

  - added a new allowable value to     '/proc/sys/kernel/wake_balance' to allow the scheduler     to run the thread on any available CPU rather than     scheduling it on the optimal CPU.

  - added 'max_writeback_pages' tunable parameter to     /proc/sys/vm/ to allow the maximum number of modified     pages kupdate writes to disk, per iteration per run.

  - added 'swap_token_timeout' tunable parameter to     /proc/sys/vm/ to provide a valid hold time for the swap     out protection token.

  - added diskdump support to sata_svw driver.

  - limited physical memory to 64GB for 32-bit kernels     running on systems with more than 64GB of physical     memory to prevent boot failures.

  - improved reliability of autofs.

  - added support for 'rdattr_error' in NFSv4 readdir     requests.

  - fixed various short packet handling issues for NFSv4     readdir and sunrpc.

  - upgraded OpenFabrics Alliance Enterprise Distribution     (OFED) to version 1.4.

  - added driver support and fixes for various Wacom     tablets.

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

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&reg; 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&reg; 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)

 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
