Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • XML Ping of the Death
    An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
  • XML Entity Expansion
    An attacker submits an XML document to a target application where the XML document uses nested entity expansion to produce an excessively large output XML. XML allows the definition of macro-like structures that can be used to simplify the creation of complex structures. However, this capability can be abused to create excessive demands on a processor's CPU and memory. A small number of nested expansions can result in an exponential growth in demands on memory.
  • Inducing Account Lockout
    An attacker leverages the security functionality of the system aimed at thwarting potential attacks to launch a denial of service attack against a legitimate system user. Many systems, for instance, implement a password throttling mechanism that locks an account after a certain number of incorrect log in attempts. An attacker can leverage this throttling mechanism to lock a legitimate user out of their own account. The weakness that is being leveraged by an attacker is the very security feature that has been put in place to counteract attacks.
  • Violating Implicit Assumptions Regarding XML Content (aka XML Denial of Service (XDoS))
    XML Denial of Service (XDoS) can be applied to any technology that utilizes XML data. This is, of course, most distributed systems technology including Java, .Net, databases, and so on. XDoS is most closely associated with web services, SOAP, and Rest, because remote service requesters can post malicious XML payloads to the service provider designed to exhaust the service provider's memory, CPU, and/or disk space. The main weakness in XDoS is that the service provider generally must inspect, parse, and validate the XML messages to determine routing, workflow, security considerations, and so on. It is exactly these inspection, parsing, and validation routines that XDoS targets. There are three primary attack vectors that XDoS can navigate Target CPU through recursion: attacker creates a recursive payload and sends to service provider Target memory through jumbo payloads: service provider uses DOM to parse XML. DOM creates in memory representation of XML document, but when document is very large (for example, north of 1 Gb) service provider host may exhaust memory trying to build memory objects. XML Ping of death: attack service provider with numerous small files that clog the system. All of the above attacks exploit the loosely coupled nature of web services, where the service provider has little to no control over the service requester and any messages the service requester sends.

    descriptionThe SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.45 and fixes various bugs and security issues. The following security issues have been fixed : - Timo Warns reported an issue in the Linux implementation for GUID partitions. Users with physical access could gain access to sensitive kernel memory by adding a storage device with a specially crafted corrupted invalid partition table. (CVE-2011-1776) - The second part of this fix was not yet applied to our kernel: arch/x86/kvm/x86.c in the Linux kernel before 2.6.36.2 does not initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via read operations on the /dev/kvm device. (CVE-2010-3881) - The /proc/PID/io interface could be used by local attackers to gain information on other processes like number of password characters typed or similar. (CVE-2011-2495) - A small buffer overflow in the radio driver si4713-i2c was fixed that could potentially used by local attackers to crash the kernel or potentially execute code. (CVE-2011-2700) - A kernel information leak in the comedi driver from kernel to userspace was fixed. (CVE-2011-2909) - In the perf framework software event overflows could deadlock or delete an uninitialized timer. (CVE-2011-2918)

    descriptionThe openSUSE 11.3 kernel was updated to fix various bugs and security issues. Following security issues have been fixed: CVE-2011-1833: Added a kernel option to ensure ecryptfs is mounting only on paths belonging to the current ui, which would have allowed local attackers to potentially gain privileges via symlink attacks. CVE-2011-3363: Always check the path in CIFS mounts to avoid interesting filesystem path interaction issues and potential crashes. CVE-2011-2918: In the perf framework software event overflows could deadlock or delete an uninitialized timer. CVE-2011-3353: In the fuse filesystem, FUSE_NOTIFY_INVAL_ENTRY did not check the length of the write so the message processing could overrun and result in a BUG_ON() in fuse_copy_fill(). This flaw could be used by local users able to mount FUSE filesystems to crash the system. CVE-2011-3191: A signedness issue in CIFS could possibly have lead to to memory corruption, if a malicious server could send crafted replies to the host. CVE-2011-1776: The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel did not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allowed physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577. Following non security bugs were fixed : - drm/radeon/kms: Fix I2C mask definitions (bnc#712023). - ext4: Fix max file size and logical block counting of extent format file (bnc#706374). - TTY: pty, fix pty counting (bnc#711203). - Update Xen patches to 2.6.34.10. - xen/blkfront: fix data size for xenbus_gather in connect(). - xen/xenbus: fix xenbus_transaction_start() hang caused by double xenbus_transaction_end(). - xen/blkback: don

    descriptionUpdated kernel-rt packages that fix multiple security issues and various bugs are now available for Red Hat Enterprise MRG 2.1. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. These packages contain the Linux kernel. Security fixes : * SG_IO ioctl SCSI requests on partitions or LVM volumes could be passed to the underlying block device, allowing a privileged user to bypass restrictions and gain read and write access (and be able to issue other SCSI commands) to the entire block device. (CVE-2011-4127, Important) * A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. (CVE-2012-0044, Important) * A local, unprivileged user could use a flaw in the Performance Events implementation to cause a denial of service. (CVE-2011-2918, Moderate) * A local, unprivileged user could use flaws in the XFS file system implementation to cause a denial of service or escalate their privileges by mounting a specially crafted disk. (CVE-2011-4077, CVE-2012-0038, Moderate) * A local, unprivileged user could use a flaw in the Out of Memory (OOM) killer to monopolize memory, have their process skipped by the OOM killer, or cause other tasks to be terminated. (CVE-2011-4097, Moderate) * A local, unprivileged user could use a flaw in the key management facility to cause a denial of service. (CVE-2011-4110, Moderate) * A malicious Network File System version 4 (NFSv4) server could return a crafted reply to a GETACL request, causing a denial of service on the client. (CVE-2011-4131, Moderate) * A local attacker could use a flaw in the Journaling Block Device (JBD) to crash the system by mounting a specially crafted ext3 or ext4 disk. (CVE-2011-4132, Moderate) * A flaw in igmp_heard_query() could allow an attacker, who is able to send certain IGMP (Internet Group Management Protocol) packets to a target system, to cause a denial of service. (CVE-2012-0207, Moderate) * If lock contention during signal sending occurred when in a software interrupt handler that is using the per-CPU debug stack, the task could be scheduled out on the realtime kernel, possibly leading to debug stack corruption. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-0810, Moderate) Red Hat would like to thank Chen Haogang for reporting CVE-2012-0044; Wang Xi for reporting CVE-2012-0038; Shubham Goyal for reporting CVE-2011-4097; Andy Adamson for reporting CVE-2011-4131; and Simon McVittie for reporting CVE-2012-0207. Bug fixes : * When a sleeping task, waiting on a futex (fast userspace mutex), tried to get the spin_lock(hb->lock) RT-mutex, if the owner of the futex released the lock, the sleeping task was put on a futex proxy lock. Consequently, the sleeping task was blocked on two locks and eventually terminated in the BUG_ON() function. With this update, the WAKEUP_INPROGRESS pseudo-lock has been added to be used as a proxy lock. This pseudo-lock tells the sleeping task that it is being woken up so that the task no longer tries to get the second lock. Now, the futex code works as expected and sleeping tasks no longer crash in the described scenario. (BZ#784733) * When the CONFIG_CRYPTO_FIPS configuration option was disabled, some services such as sshd and ipsec, while working properly, returned warning messages regarding this missing option during start up. With this update, CONFIG_CRYPTO_FIPS has been enabled and no warning messages are now returned in the described scenario. (BZ#786145) * Previously, when a read operation on a loop device failed, the data successfully read from the device was not cleared and could eventually leak. This bug has been fixed and all data are now properly cleared in the described scenario. (BZ#761420) * Due to an assembler-sourced object, the perf utility (from the perf-rt package) for AMD64 and Intel 64 architectures contained an executable stack. This update adds the

    NASL idSUSE_11_4_KERNEL-111026.NASL
    descriptionThe openSUSE 11.4 kernel was updated to 2.6.37.6 fixing lots of bugs and security issues. Following security issues have been fixed: CVE-2011-1833: Added a kernel option to ensure ecryptfs is mounting only on paths belonging to the current ui, which would have allowed local attackers to potentially gain privileges via symlink attacks. CVE-2011-2695: Multiple off-by-one errors in the ext4 subsystem in the Linux kernel allowed local users to cause a denial of service (BUG_ON and system crash) by accessing a sparse file in extent format with a write operation involving a block number corresponding to the largest possible 32-bit unsigned integer. CVE-2011-3363: Always check the path in CIFS mounts to avoid interesting filesystem path interaction issues and potential crashes. CVE-2011-2918: In the perf framework software event overflows could deadlock or delete an uninitialized timer. CVE-2011-3353: In the fuse filesystem, FUSE_NOTIFY_INVAL_ENTRY did not check the length of the write so the message processing could overrun and result in a BUG_ON() in fuse_copy_fill(). This flaw could be used by local users able to mount FUSE filesystems to crash the system. CVE-2011-2183: Fixed a race between ksmd and other memory management code, which could result in a NULL ptr dereference and kernel crash. CVE-2011-3191: A signedness issue in CIFS could possibly have lead to to memory corruption, if a malicious server could send crafted replies to the host. CVE-2011-1776: The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel did not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allowed physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577. Following non-security bugs were fixed : - novfs: Unable to change password in the Novell Client for Linux (bnc#713229). - novfs: last modification time not reliable (bnc#642896). - novfs: unlink directory after unmap (bnc#649625). - fs: novfs: Fix exit handlers on local_unlink (bnc#649625). - novfs:

    titleUSN-1212-1 : linux-ti-omap4 vulnerabilities
  • NASL familyAmazon Linux Local Security Checks
    NASL idALA_ALAS-2011-16.NASL
    descriptionThe skb_gro_header_slow function in include/linux/netdevice.h in the Linux kernel before 2.6.39.4, when Generic Receive Offload (GRO) is enabled, resets certain fields in incorrect situations, which allows remote attackers to cause a denial of service (system crash) via crafted network traffic. Race condition in the ecryptfs_mount function in fs/ecryptfs/main.c in the eCryptfs subsystem in the Linux kernel before 3.1 allows local users to bypass intended file permissions via a mount.ecryptfs_private mount with a mismatched uid. The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets. Integer signedness error in the CIFSFindNext function in fs/cifs/cifssmb.c in the Linux kernel before 3.1 allows remote CIFS servers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large length value in a response to a read request for a directory. The Performance Events subsystem in the Linux kernel before 3.1 does not properly handle event overflows associated with PERF_COUNT_SW_CPU_CLOCK events, which allows local users to cause a denial of service (system hang) via a crafted application.
