- Olaf Kirch reported a flaw in the i915 kernel driver     that only affects the Intel G33 series and newer. This     flaw could, potentially, lead to local privilege     escalation. (CVE-2008-3831, Important)

  - Miklos Szeredi reported a missing check for files opened     with O_APPEND in the sys_splice(). This could allow a     local, unprivileged user to bypass the append-only file     restrictions. (CVE-2008-4554, Important)

  - a deficiency was found in the Linux kernel Stream     Control Transmission Protocol (SCTP) implementation.
    This could lead to a possible denial of service if one     end of a SCTP connection did not support the AUTH     extension. (CVE-2008-4576, Important)

In addition, these updated packages fix the following bugs :

  - on Itanium&reg; systems, when a multithreaded program     was traced using the command 'strace -f', messages     similar to the following ones were displayed, after     which the trace would stop :

    PANIC: attached pid 10740 exited PANIC:
    handle_group_exit: 10740 leader 10721 PANIC: attached     pid 10739 exited PANIC: handle_group_exit: 10739 leader     10721 ...

In these updated packages, tracing a multithreaded program using the 'strace -f' command no longer results in these error messages, and strace terminates normally after tracing all threads.

  - on big-endian systems such as PowerPC, the getsockopt()     function incorrectly returned 0 depending on the     parameters passed to it when the time to live (TTL)     value equaled 255.

  - when using an NFSv4 file system, accessing the same file     with two separate processes simultaneously resulted in     the NFS client process becoming unresponsive.

  - on AMD64 and Intel&reg; 64 hypervisor-enabled systems,     in cases in which a syscall correctly returned '-1' in     code compiled on Red Hat Enterprise Linux 5, the same     code, when run with the strace utility, would     incorrectly return an invalid return value. This has     been fixed so that on AMD64 and Intel&reg; 64     hypervisor-enabled systems, syscalls in compiled code     return the same, correct values as syscalls do when run     with strace.

  - on the Itanium&reg; architecture, fully-virtualized     guest domains which were created using more than 64 GB     of memory caused other guest domains not to receive     interrupts, which caused a soft lockup on other guests.
    All guest domains are now able to receive interrupts     regardless of their allotted memory.

  - when user-space used SIGIO notification, which wasn't     disabled before closing a file descriptor, and was then     re-enabled in a different process, an attempt by the     kernel to dereference a stale pointer led to a kernel     crash. With this fix, such a situation no longer causes     a kernel crash.

  - modifications to certain pages made through a     memory-mapped region could have been lost in cases when     the NFS client needed to invalidate the page cache for     that particular memory-mapped file.

  - fully-virtualized Windows guests became unresponsive due     to the vIOSAPIC component being multiprocessor-unsafe.
    With this fix, vIOSAPIC is multiprocessor-safe and     Windows guests do not become unresponsive.

  - on certain systems, keyboard controllers were not able     to withstand a continuous flow of requests to switch     keyboard LEDs on or off, which resulted in some or all     key presses not being registered by the system.

  - on the Itanium&reg; architecture, setting the     'vm.nr_hugepages' sysctl parameter caused a kernel stack     overflow resulting in a kernel panic, and possibly stack     corruption. With this fix, setting vm.nr_hugepages works     correctly.

  - hugepages allow the Linux kernel to utilize the multiple     page size capabilities of modern hardware architectures.
    In certain configurations, systems with large amounts of     memory could fail to allocate most of memory for     hugepages even if it was free, which could have     resulted, for example, in database restart failures.

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-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-2009-1265: 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-2009-0676: 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.

CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c in the Linux kernel might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call.

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 resolve several security issues and fix various 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.

* Olaf Kirch reported a flaw in the i915 kernel driver. This flaw could, potentially, lead to local privilege escalation. Note: the flaw only affects systems based on the Intel G33 Express Chipset and newer.
(CVE-2008-3831, Important)

* Miklos Szeredi reported a missing check for files opened with O_APPEND in the sys_splice(). This could allow a local, unprivileged user to bypass the append-only file restrictions. (CVE-2008-4554, Important)

* a deficiency was found in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. This could lead to a possible denial of service if one end of a SCTP connection did not support the AUTH extension. (CVE-2008-4576, Important)

In addition, these updated packages fix the following bugs :

* on Itanium(r) systems, when a multithreaded program was traced using the command 'strace -f', messages such as

PANIC: attached pid 10740 exited PANIC: handle_group_exit: 10740 leader 10721 ...

will be displayed, and after which the trace would stop. With these updated packages, 'strace -f' command no longer results in these error messages, and strace terminates normally after tracing all threads.

* on big-endian systems such as PowerPC, the getsockopt() function incorrectly returned 0 depending on the parameters passed to it when the time to live (TTL) value equaled 255.

* when using an NFSv4 file system, accessing the same file with two separate processes simultaneously resulted in the NFS client process becoming unresponsive.

* hugepages allow the Linux kernel to utilize the multiple page size capabilities of modern hardware architectures. In certain configurations, systems with large amounts of memory could fail to allocate most of this memory for hugepages even if it was free. This could result, for example, in database restart failures.

Users should upgrade to these updated packages, which contain backported patches to correct these issues.

Update kernel from version 2.6.26.5 to 2.6.26.6:
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.26.6 CVE-2008-3831 An IOCTL in the i915 driver was not properly restricted to users with the proper capabilities to use it. CVE-2008-4410 The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes write_idt_entry where write_ldt_entry was intended, which allows local users to cause a denial of service (persistent application failure) via crafted function calls, related to the Java Runtime Environment (JRE) experiencing improper LDT selector state, a different vulnerability than CVE-2008-3247. CVE-2008-3525 The sbni_ioctl function in drivers/net/wan/sbni.c in the wan subsystem in the Linux kernel 2.6.26.3 does not check for the CAP_NET_ADMIN capability before processing a (1) SIOCDEVRESINSTATS, (2) SIOCDEVSHWSTATE, (3) SIOCDEVENSLAVE, or (4) SIOCDEVEMANSIPATE ioctl request, which allows local users to bypass intended capability restrictions. CVE-2008-4554 The do_splice_from function in fs/splice.c in the Linux kernel before 2.6.27 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. CVE-2008-4576 sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2008-3528     Eugene Teo reported a local DoS issue in the ext2 and     ext3 filesystems. Local users who have been granted the     privileges necessary to mount a filesystem would be able     to craft a corrupted filesystem that causes the kernel     to output error messages in an infinite loop.

  - CVE-2008-4554     Milos Szeredi reported that the usage of splice() on     files opened with O_APPEND allows users to write to the     file at arbitrary offsets, enabling a bypass of possible     assumed semantics of the O_APPEND flag.

  - CVE-2008-4576     Vlad Yasevich reported an issue in the SCTP subsystem     that may allow remote users to cause a local DoS by     triggering a kernel oops.

  - CVE-2008-4933     Eric Sesterhenn reported a local DoS issue in the     hfsplus filesystem. Local users who have been granted     the privileges necessary to mount a filesystem would be     able to craft a corrupted filesystem that causes the     kernel to overrun a buffer, resulting in a system oops     or memory corruption.

  - CVE-2008-4934     Eric Sesterhenn reported a local DoS issue in the     hfsplus filesystem. Local users who have been granted     the privileges necessary to mount a filesystem would be     able to craft a corrupted filesystem that results in a     kernel oops due to an unchecked return value.

  - CVE-2008-5025     Eric Sesterhenn reported a local DoS issue in the hfs     filesystem. Local users who have been granted the     privileges necessary to mount a filesystem would be able     to craft a filesystem with a corrupted catalog name     length, resulting in a system oops or memory corruption.

  - CVE-2008-5029     Andrea Bittau reported a DoS issue in the unix socket     subsystem that allows a local user to cause memory     corruption, resulting in a kernel panic.

  - CVE-2008-5134     Johannes Berg reported a remote DoS issue in the     libertas wireless driver, which can be triggered by a     specially crafted beacon/probe response.

  - CVE-2008-5182     Al Viro reported race conditions in the inotify     subsystem that may allow local users to acquire elevated     privileges.

  - CVE-2008-5300     Dann Frazier reported a DoS condition that allows local     users to cause the out of memory handler to kill off     privileged processes or trigger soft lockups due to a     starvation issue in the unix socket subsystem.

  - CVE-2008-5079     Hugo Dias reported a DoS condition in the ATM subsystem     that can be triggered by a local user by calling the     svc_listen function twice on the same socket and reading     /proc/net/atm/*vc.

  - CVE-2008-5182     Al Viro reported race conditions in the inotify     subsystem that may allow local users to acquire elevated     privileges.

  - CVE-2008-5300     Dann Frazier reported a DoS condition that allows local     users to cause the out of memory handler to kill off     privileged processes or trigger soft lockups due to a     starvation issue in the unix socket subsystem.

It was discovered that the Xen hypervisor block driver did not correctly validate requests. A user with root privileges in a guest OS could make a malicious IO request with a large number of blocks that would crash the host OS, leading to a denial of service. This only affected Ubuntu 7.10. (CVE-2007-5498)

It was discovered the the i915 video driver did not correctly validate memory addresses. A local attacker could exploit this to remap memory that could cause a system crash, leading to a denial of service. This issue did not affect Ubuntu 6.06 and was previous fixed for Ubuntu 7.10 and 8.04 in USN-659-1. Ubuntu 8.10 has now been corrected as well. (CVE-2008-3831)

David Watson discovered that the kernel did not correctly strip permissions when creating files in setgid directories. A local user could exploit this to gain additional group privileges. This issue only affected Ubuntu 6.06. (CVE-2008-4210)

Olaf Kirch and Miklos Szeredi discovered that the Linux kernel did not correctly reject the 'append' flag when handling file splice requests.
A local attacker could bypass append mode and make changes to arbitrary locations in a file. This issue only affected Ubuntu 7.10 and 8.04. (CVE-2008-4554)

It was discovered that the SCTP stack did not correctly handle INIT-ACK. A remote user could exploit this by sending specially crafted SCTP traffic which would trigger a crash in the system, leading to a denial of service. This issue did not affect Ubuntu 8.10.
(CVE-2008-4576)

It was discovered that the SCTP stack did not correctly handle bad packet lengths. A remote user could exploit this by sending specially crafted SCTP traffic which would trigger a crash in the system, leading to a denial of service. This issue did not affect Ubuntu 8.10.
(CVE-2008-4618)

Eric Sesterhenn discovered multiple flaws in the HFS+ filesystem. If a local user or automated system were tricked into mounting a malicious HFS+ filesystem, the system could crash, leading to a denial of service. (CVE-2008-4933, CVE-2008-4934, CVE-2008-5025)

It was discovered that the Unix Socket handler did not correctly process the SCM_RIGHTS message. A local attacker could make a malicious socket request that would crash the system, leading to a denial of service. (CVE-2008-5029)

It was discovered that the driver for simple i2c audio interfaces did not correctly validate certain function pointers. A local user could exploit this to gain root privileges or crash the system, leading to a denial of service. (CVE-2008-5033).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

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-2008-3528)

The i915 driver in (1) drivers/char/drm/i915_dma.c in the Linux kernel 2.6.24 on Debian GNU/Linux and (2) sys/dev/pci/drm/i915_drv.c in OpenBSD does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration. (CVE-2008-3831)

The do_splice_from function in fs/splice.c in the Linux kernel before 2.6.27 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. (CVE-2008-4554)

Additionaly, a problem with TCP options ordering, which could manifest as connection problems with many websites (bug #43372), was solved, a number of fixes for Intel HDA were added, another number of fixes for issues on Asus EEE PC, Panasonic Let's Note, Acer One, Dell XPS, and others, were also added. Check package changelog for more information.

Update :

The previous update included a patch which introduced a bug that would make the boot process to stop halfway in several machines. That patch has been removed in this new update, to avoid that problem.

This update fixes various security issues and several bugs in the openSUSE 11.0 kernel. It was also updated to the stable version 2.6.25.20.

CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call.

CVE-2008-5700: libata did 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-2008-5079: net/atm/svc.c in the ATM subsystem allowed 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-2008-5300: Linux kernel 2.6.28 allows local users to cause a denial of service ('soft lockup' and process loss) via a large number of sendmsg function calls, which does not block during AF_UNIX garbage collection and triggers an OOM condition, a different vulnerability than CVE-2008-5029.

CVE-2008-5029: The __scm_destroy function in net/core/scm.c makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors.

CVE-2008-4933: Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function.

CVE-2008-5025: Stack-based buffer overflow in the hfs_cat_find_brec function in fs/hfs/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfs filesystem image with an invalid catalog namelength field, a related issue to CVE-2008-4933.

CVE-2008-5182: The inotify functionality might allow local users to gain privileges via unknown vectors related to race conditions in inotify watch removal and umount.

CVE-2008-3831: The i915 driver in drivers/char/drm/i915_dma.c does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration.

CVE-2008-4554: The do_splice_from function in fs/splice.c did 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.

The remote CentOS system is missing a security update which has been documented in Red Hat advisory RHSA-2008-1017.
