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.

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in the following components :

  - Apache Geronimo
  - Apache Tomcat
  - Apache Xerces2
  - 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 Provider
  - Java SE Swing
  - Java SE Web Start

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

CVE-2008-3528 The error-reporting functionality in (1) fs/ext2/dir.c, (2) fs/ext3/dir.c, and possibly (3) fs/ext4/dir.c in the Linux kernel 2.6.26.5 does not limit the number of printk console messages that report directory corruption, which allows physically proximate attackers to cause a denial of service (temporary system hang) by mounting a filesystem that has corrupted dir->i_size and dir->i_blocks values and performing (a) read or (b) write operations. NOTE: there are limited scenarios in which this crosses privilege boundaries.

CVE-2008-5700 libata in the Linux kernel before 2.6.27.9 does not set minimum timeouts for SG_IO requests, which allows local users to cause a denial of service (Programmed I/O mode on drives) via multiple simultaneous invocations of an unspecified test program.

CVE-2009-0028 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-2009-0322 drivers/firmware/dell_rbu.c in the Linux kernel before 2.6.27.13, and 2.6.28.x before 2.6.28.2, 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-2009-0675 The skfp_ioctl function in drivers/net/skfp/skfddi.c in the Linux kernel before 2.6.28.6 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 before 2.6.28.6 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.

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 :

* 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.

(CVE-2009-0028, Moderate)

* an off-by-one underflow flaw was found in the eCryptfs subsystem.
This could potentially cause a local denial of service when the readlink() function returned an error. (CVE-2009-0269, Moderate)

* a deficiency was found in the Remote BIOS Update (RBU) driver for Dell systems. This could allow a local, unprivileged user to cause a denial of service by reading zero bytes from the image_type or packet_size files in '/sys/devices/platform/dell_rbu/'.
(CVE-2009-0322, Moderate)

(CVE-2009-0676, Moderate)

* the ext2 and ext3 file system code failed to properly handle corrupted data structures, leading to a possible local denial of service when read or write operations were performed on a specially crafted file system. (CVE-2008-3528, Low)

* a deficiency was found in the libATA implementation. This could, potentially, lead to a local denial of service. Note: by default, the '/dev/sg*' devices are accessible only to the root user.
(CVE-2008-5700, Low)

Bug fixes :

* a bug in aic94xx may have caused kernel panics during boot on some systems with certain SATA disks. (BZ#485909)

* a word endianness problem in the qla2xx driver on PowerPC-based machines may have corrupted flash-based devices. (BZ#485908)

* CPU soft-lockups in the network rate estimator. (BZ#481746)

* bugs in the ixgbe driver caused it to function unreliably on some systems with 16 or more CPU cores. (BZ#483210)

* the iwl4965 driver may have caused a kernel panic. (BZ#483206)

* a bug caused NFS attributes to not update for some long-lived NFS mounted file systems. (BZ#483201)

* a bug in ptrace() may have caused a panic when single stepping a target. (BZ#487394)

* on some 64-bit systems, notsc was incorrectly set at boot, causing slow gettimeofday() calls. (BZ#488239)

* 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#490433)

* scaling problems caused performance problems for LAPI applications.
(BZ#489457)

* a panic may have occurred on systems using certain Intel WiFi Link 5000 products when booting with the RF Kill switch on. (BZ#489846)

This Linux kernel update for SUSE Linux Enterprise 10 Service Pack 2 fixes various bugs and several security issues.

The following security issues were fixed: 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.

  - 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-2009-0676)

  - 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-2009-0028)

  - The Linux kernel does not check when a user attempts to     set RLIMIT_CPU to 0 until after the change is made,     which allows local users to bypass intended resource     limits. (CVE-2008-1294)

  - 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. (CVE-2009-0065)

  - The console selection feature in the Linux kernel when     the UTF-8 console is used, allows physically proximate     attackers to cause a denial of service (memory     corruption) by selecting a small number of 3-byte UTF-8     characters, which triggers an an off-by-two memory     error. It is is not clear if this can be exploited at     all. (CVE-2009-1046)

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

 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 update fixes several security issues and hundreds of bugs in the openSUSE 11.1 kernel.

The kernel was also updated to the stable version 2.6.27.19 and is now the same kernel as we are planning to ship with SUSE Linux Enterprise 11.

This introduces kABI changes, so all kernel module packages also need to be rebuilt and reapplied.

Following security issues are fixed: CVE-2009-0029: The ABI in the Linux kernel on s390, powerpc, sparc64, and mips 64-bit platforms requires that a 32-bit argument in a 64-bit register was properly sign extended when sent from a user-mode application, but cannot verify this, which allows local users to cause a denial of service (crash) or possibly gain privileges via a crafted system call.

CVE-2008-5079: net/atm/svc.c in the ATM subsystem in the Linux kernel allows local users to cause a denial of service (kernel infinite loop) by making two calls to svc_listen for the same socket, and then reading a /proc/net/atm/*vc file, related to corruption of the vcc table.

CVE-2009-0028: A minor signal handling vulnerability was fixed, where a child could send his parent a arbitrary signal.

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.

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

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-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.
