net/atm/svc.c in the ATM subsystem in the Linux kernel 2.6.27.8 and earlier 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.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2009-0225 advisory.

  - The __scm_destroy function in net/core/scm.c in the Linux kernel 2.6.27.4, 2.6.26, and earlier 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-2008-5029)

  - net/atm/svc.c in the ATM subsystem in the Linux kernel 2.6.27.8 and earlier 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-2008-5079)

  - The inotify functionality in Linux kernel 2.6 before 2.6.28-rc5 might allow local users to gain privileges     via unknown vectors related to race conditions in inotify watch removal and umount. (CVE-2008-5182)

  - 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-2008-5300)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated kernel packages that resolve several security issues 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 includes backported fixes for four security issues. These issues only affected users of Red Hat Enterprise Linux 5.2 Extended Update Support as they have already been addressed for users of Red Hat Enterprise Linux 5 in the 5.3 update, RHSA-2009:0225.

In accordance with the support policy, future security updates to Red Hat Enterprise Linux 5.2 Extended Update Support will only include issues of critical security impact.

* when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue.
(CVE-2008-5029, Important)

* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)

* a flaw was found in the Asynchronous Transfer Mode (ATM) subsystem.
A local, unprivileged user could use the flaw to listen on the same socket more than once, possibly causing a denial of service.
(CVE-2008-5079, Important)

* a race condition was found in the Linux kernel 'inotify' watch removal and umount implementation. This could allow a local, unprivileged user to cause a privilege escalation or a denial of service. (CVE-2008-5182, Important)

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

This update addresses the following security issues :

  - a memory leak in keyctl handling. A local user could use     this flaw to deplete kernel memory, eventually leading     to a denial of service. (CVE-2009-0031, Important)

  - a buffer overflow in the Linux kernel Partial Reliable     Stream Control Transmission Protocol (PR-SCTP)     implementation. This could, potentially, lead to a     denial of service if a Forward-TSN chunk is received     with a large stream ID. (CVE-2009-0065, Important)

  - a flaw when handling heavy network traffic on an SMP     system with many cores. An attacker who could send a     large amount of network traffic could create a denial of     service. (CVE-2008-5713, Important)

  - the code for the HFS and HFS Plus (HFS+) file systems     failed to properly handle corrupted data structures.
    This could, potentially, lead to a local denial of     service. (CVE-2008-4933, CVE-2008-5025, Low)

  - a flaw was found in the HFS Plus (HFS+) file system     implementation. This could, potentially, lead to a local     denial of service when write operations are performed.
    (CVE-2008-4934, Low)

  - when fput() was called to close a socket, the
    __scm_destroy() function in the Linux kernel could make     indirect recursive calls to itself. This could,     potentially, lead to a denial of service issue.
    (CVE-2008-5029, Important)

  - a flaw was found in the Asynchronous Transfer Mode (ATM)     subsystem. A local, unprivileged user could use the flaw     to listen on the same socket more than once, possibly     causing a denial of service. (CVE-2008-5079, Important)

  - a race condition was found in the Linux kernel 'inotify'     watch removal and umount implementation. This could     allow a local, unprivileged user to cause a privilege     escalation or a denial of service. (CVE-2008-5182,     Important)

  - when using the nfsd daemon in a clustered setup, kernel     panics appeared seemingly at random. These panics were     caused by a race condition in the device-mapper mirror     target.

  - the clock_gettime(CLOCK_THREAD_CPUTIME_ID, ) syscall     returned a smaller timespec value than the result of     previous clock_gettime() function execution, which     resulted in a negative, and nonsensical, elapsed time     value.

  - nfs_create_rpc_client was called with a 'flavor'     parameter which was usually ignored and ended up     unconditionally creating the RPC client with an     AUTH_UNIX flavor. This caused problems on AUTH_GSS     mounts when the credentials needed to be refreshed. The     credops did not match the authorization type, which     resulted in the credops dereferencing an incorrect part     of the AUTH_UNIX rpc_auth struct.

  - when copy_user_c terminated prematurely due to reading     beyond the end of the user buffer and the kernel jumped     to the exception table entry, the rsi register was not     cleared. This resulted in exiting back to user code with     garbage in the rsi register.

  - the hexdump data in s390dbf traces was incomplete. The     length of the data traced was incorrect and the SAN     payload was read from a different place then it was     written to.

  - when using connected mode (CM) in IPoIB on ehca2     hardware, it was not possible to transmit any data.

  - when an application called fork() and pthread_create()     many times and, at some point, a thread forked a child     and then attempted to call the setpgid() function, then     this function failed and returned and ESRCH error value.

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

The following security problems have been fixed :

  - 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-2008-5079)

  - 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-2008-5029)

  - 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-2008-4933)

  - 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-2008-5025)

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

A lot of other bugs were fixed, a detailed list can be found in the RPM changelog.

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 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.

* a flaw was found in the Asynchronous Transfer Mode (ATM) subsystem.
A local, unprivileged user could use the flaw to listen on the same socket more than once, possibly causing a denial of service.
(CVE-2008-5079, Important)

* a race condition was found in the Linux kernel 'inotify' watch removal and umount implementation. This could allow a local, unprivileged user to cause a privilege escalation or a denial of service. (CVE-2008-5182, Important)
