Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.

    descriptionUpdated kernel packages that fix various 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. Security fixes : * a missing capability check was found in the Linux kernel do_change_type routine. This could allow a local unprivileged user to gain privileged access or cause a denial of service. (CVE-2008-2931, Important) * a flaw was found in the Linux kernel Direct-IO implementation. This could allow a local unprivileged user to cause a denial of service. (CVE-2007-6716, Important) * Tobias Klein reported a missing check in the Linux kernel Open Sound System (OSS) implementation. This deficiency could lead to a possible information leak. (CVE-2008-3272, Moderate) * a deficiency was found in the Linux kernel virtual filesystem (VFS) implementation. This could allow a local unprivileged user to attempt file creation within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate) * a flaw was found in the Linux kernel tmpfs implementation. This could allow a local unprivileged user to read sensitive information from the kernel. (CVE-2007-6417, Moderate) Bug fixes : * when copying a small IPoIB packet from the original skb it was received in to a new, smaller skb, all fields in the new skb were not initialized. This may have caused a kernel oops. * previously, data may have been written beyond the end of an array, causing memory corruption on certain systems, resulting in hypervisor crashes during context switching. * a kernel crash may have occurred on heavily-used Samba servers after 24 to 48 hours of use. * under heavy memory pressure, pages may have been swapped out from under the SGI Altix XPMEM driver, causing silent data corruption in the kernel. * the ixgbe driver is untested, but support was advertised for the Intel 82598 network card. If this card was present when the ixgbe driver was loaded, a NULL pointer dereference and a panic occurred. * on certain systems, if multiple InfiniBand queue pairs simultaneously fell into an error state, an overrun may have occurred, stopping traffic. * with bridging, when forward delay was set to zero, setting an interface to the forwarding state was delayed by one or possibly two timers, depending on whether STP was enabled. This may have caused long delays in moving an interface to the forwarding state. This issue caused packet loss when migrating virtual machines, preventing them from being migrated without interrupting applications. * on certain multinode systems, IPMI device nodes were created in reverse order of where they physically resided. * process hangs may have occurred while accessing application data files via asynchronous direct I/O system calls. * on systems with heavy lock traffic, a possible deadlock may have caused anything requiring locks over NFS to stop, or be very slow.

    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 missing capability check was found in the Linux kernel
    do_change_type routine. This could allow a local unprivileged user to
    gain privileged access or cause a denial of service. (CVE-2008-2931,

    * a flaw was found in the Linux kernel Direct-IO implementation. This
    could allow a local unprivileged user to cause a denial of service.
    (CVE-2007-6716, Important)
    
    * Tobias Klein reported a missing check in the Linux kernel Open Sound
    System (OSS) implementation. This deficiency could lead to a possible
    information leak. (CVE-2008-3272, Moderate)
    
    * a deficiency was found in the Linux kernel virtual filesystem (VFS)
    implementation. This could allow a local unprivileged user to attempt

    * a flaw was found in the Linux kernel tmpfs implementation. This
    could allow a local unprivileged user to read sensitive information
    from the kernel. (CVE-2007-6417, Moderate)
    
    Bug fixes :
    
    * when copying a small IPoIB packet from the original skb it was
    received in to a new, smaller skb, all fields in the new skb were not
    initialized. This may have caused a kernel oops.
    
    * previously, data may have been written beyond the end of an array,
    causing memory corruption on certain systems, resulting in hypervisor
    crashes during context switching.
    
    * a kernel crash may have occurred on heavily-used Samba servers after
    24 to 48 hours of use.
    
    * under heavy memory pressure, pages may have been swapped out from
    under the SGI Altix XPMEM driver, causing silent data corruption in
    the kernel.
    
    * the ixgbe driver is untested, but support was advertised for the
    Intel 82598 network card. If this card was present when the ixgbe
    driver was loaded, a NULL pointer dereference and a panic occurred.
    
    * on certain systems, if multiple InfiniBand queue pairs
    simultaneously fell into an error state, an overrun may have occurred,
    stopping traffic.
    
    * with bridging, when forward delay was set to zero, setting an
    interface to the forwarding state was delayed by one or possibly two
    timers, depending on whether STP was enabled. This may have caused
    long delays in moving an interface to the forwarding state. This issue
    caused packet loss when migrating virtual machines, preventing them
    from being migrated without interrupting applications.
    
    * on certain multinode systems, IPMI device nodes were created in
    reverse order of where they physically resided.
    
    * process hangs may have occurred while accessing application data
    files via asynchronous direct I/O system calls.
    
    * on systems with heavy lock traffic, a possible deadlock may have
    caused anything requiring locks over NFS to stop, or be very slow.
    Errors such as 'lockd: server [IP] not responding, timed out' were
    logged on client systems.
    
    * unexpected removals of USB devices may have caused a NULL pointer
    dereference in kobject_get_path.
    
    * on Itanium-based systems, repeatedly creating and destroying Windows
    guests may have caused Dom0 to crash, due to the
    'XENMEM_add_to_physmap' hypercall, used by para-virtualized drivers on
    HVM, being SMP-unsafe.
    
    * when using an MD software RAID, crashes may have occurred when
    devices were removed or changed while being iterated through. Correct
    locking is now used.
    
    * break requests had no effect when using 'Serial Over Lan' with the
    Intel 82571 network card. This issue may have caused log in problems.
    
    * on Itanium-based systems, module_free() referred the first parameter
    before checking it was valid. This may have caused a kernel panic when
    exiting SystemTap.
    
    Red Hat Enterprise Linux 5 users are advised to upgrade to these
    updated packages, which contain backported patches to resolve these
    issues."

        application data files via asynchronous direct I/O
        system calls.
    
      - on systems with heavy lock traffic, a possible deadlock
        may have caused anything requiring locks over NFS to
        stop, or be very slow. Errors such as 'lockd: server
        [IP] not responding, timed out' were logged on client

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or arbitrary code execution. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2007-6282 Dirk Nehring discovered a vulnerability in the IPsec code that allows remote users to cause a denial of service by sending a specially crafted ESP packet. - CVE-2008-0598 Tavis Ormandy discovered a vulnerability that allows local users to access uninitialized kernel memory, possibly leaking sensitive data. This issue is specific to the amd64-flavour kernel images. - CVE-2008-2729 Andi Kleen discovered an issue where uninitialized kernel memory was being leaked to userspace during an exception. This issue may allow local users to gain access to sensitive data. Only the amd64-flavour Debian kernel images are affected. - CVE-2008-2812 Alan Cox discovered an issue in multiple tty drivers that allows local users to trigger a denial of service (NULL pointer dereference) and possibly obtain elevated privileges. - CVE-2008-2826 Gabriel Campana discovered an integer overflow in the sctp code that can be exploited by local users to cause a denial of service. - CVE-2008-2931 Miklos Szeredi reported a missing privilege check in the do_change_type() function. This allows local, unprivileged users to change the properties of mount points. - CVE-2008-3272 Tobias Klein reported a locally exploitable data leak in the snd_seq_oss_synth_make_info() function. This may allow local users to gain access to sensitive information. - CVE-2008-3275 Zoltan Sogor discovered a coding error in the VFS that allows local users to exploit a kernel memory leak resulting in a denial of service.

(CVE-2008-3525) - On AMD64 some string operations could leak kernel information into userspace. (CVE-2008-0598) - Added range checking in ASN.1 handling for the CIFS and SNMP NAT netfilter modules.

(CVE-2008-3272) - Fixed a memory leak when looking up deleted directories which could be used to run the system out of memory. (CVE-2008-3275) - The do_change_type function in fs/namespace.c did not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint. (CVE-2008-2931) - Various NULL ptr checks have been added to tty op functions, which might have been used by local attackers to execute code.

    descriptionIt was discovered that there were multiple NULL pointer function dereferences in the Linux kernel terminal handling code. A local attacker could exploit this to execute arbitrary code as root, or crash the system, leading to a denial of service. (CVE-2008-2812) The do_change_type routine did not correctly validation administrative users. A local attacker could exploit this to block mount points or cause private mounts to be shared, leading to denial of service or a possible loss of privacy. (CVE-2008-2931) Tobias Klein discovered that the OSS interface through ALSA did not correctly validate the device number. A local attacker could exploit this to access sensitive kernel memory, leading to a denial of service or a loss of privacy. (CVE-2008-3272) Zoltan Sogor discovered that new directory entries could be added to already deleted directories. A local attacker could exploit this, filling up available memory and disk space, leading to a denial of service. (CVE-2008-3275) In certain situations, the fix for CVE-2008-0598 from USN-623-1 was causing infinite loops in the writev syscall. This update corrects the mistake. We apologize for the inconvenience. 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.

Only this problem was fixed additionally. This kernel update fixes the following security problems : - On x86_64 a denial of service attack could be used by local attackers to immediately panic / crash the machine. (CVE-2008-1615) - Fixed a SMP ordering problem in fcntl_setlk could potentially allow local attackers to execute code by timing file locking. (CVE-2008-1669) - Fixed a resource starvation problem in the handling of ZERO mmap pages. (CVE-2008-2372) - The asn1 implementation in (a) the Linux kernel, as used in the cifs and ip_nat_snmp_basic modules does not properly validate length values during decoding of ASN.1 BER data, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via (1) a length greater than the working buffer, which can lead to an unspecified overflow; (2) an oid length of zero, which can lead to an off-by-one error; or (3) an indefinite length for a primitive encoding. (CVE-2008-1673) - Various tty / serial devices did not check functionpointers for NULL before calling them, leading to potential crashes or code execution. The devices affected are usually only accessible by the root user though. (CVE-2008-2812) - A missing permission check in mount changing was added which could have been used by local attackers to change the mountdirectory. (CVE-2008-2931) Additionally a very large number of bugs was fixed. Details can be found in the RPM changelog of the included packages. OCFS2 has been upgraded to the 1.4.1 release : - Endian fixes - Use slab caches for DLM objects - Export DLM state info to debugfs - Avoid ENOSPC in rare conditions when free inodes are reserved by other nodes - Error handling fix in ocfs2_start_walk_page_trans() - Cleanup lockres printing - Allow merging of extents - Fix to allow changing permissions of symlinks - Merged local fixes upstream (no code change)

    descriptionThis kernel update fixes various bugs and also several security issues : CVE-2008-4576: Fixed a crash in SCTP INIT-ACK, on mismatch between SCTP AUTH availability. This might be exploited remotely for a denial of service (crash) attack. CVE-2008-3833: The generic_file_splice_write function in fs/splice.c in the Linux kernel does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by splicing into an inode in order to create an executable file in a setgid directory. CVE-2008-4210: fs/open.c in the Linux kernel before 2.6.22 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by creating an executable file in a setgid directory through the (1) truncate or (2) ftruncate function in conjunction with memory-mapped I/O. CVE-2008-4302: fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool. CVE-2008-3528: The ext[234] filesystem code fails to properly handle corrupted data structures. With a mounted filesystem image or partition that have corrupted dir->i_size and dir->i_blocks, a user performing either a read or write operation on the mounted image or partition can lead to a possible denial of service by spamming the logfile. CVE-2007-6716: fs/direct-io.c in the dio subsystem in the Linux kernel did not properly zero out the dio struct, which allows local users to cause a denial of service (OOPS), as demonstrated by a certain fio test. CVE-2008-3525: Added missing capability checks in sbni_ioctl(). CVE-2008-3272: Fixed range checking in the snd_seq OSS ioctl, which could be used to leak information from the kernel. CVE-2008-2931: The do_change_type function in fs/namespace.c did not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint.
