Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

    descriptionSeveral 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-2011-2183 Andrea Righi reported an issue in KSM, a memory-saving de-duplication feature. By exploiting a race with exiting tasks, local users can cause a kernel oops, resulting in a denial of service. - CVE-2011-2213 Dan Rosenberg discovered an issue in the INET socket monitoring interface. Local users could cause a denial of service by injecting code and causing the kernel to execute an infinite loop. - CVE-2011-2898 Eric Dumazet reported an information leak in the raw packet socket implementation. - CVE-2011-3353 Han-Wen Nienhuys reported a local denial of service issue in the FUSE (Filesystem in Userspace) support in the Linux kernel. Local users could cause a buffer overflow, leading to a kernel oops and resulting in a denial of service. - CVE-2011-4077 Carlos Maiolino reported an issue in the XFS filesystem. A local user with the ability to mount a filesystem could corrupt memory resulting in a denial of service or possibly gain elevated privileges. - CVE-2011-4110 David Howells reported an issue in the kernel

"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-2011-2183
    Andrea Righi reported an issue in KSM, a memory-saving
    de-duplication feature. By exploiting a race with
    exiting tasks, local users can cause a kernel oops,
    resulting in a denial of service.

  - CVE-2011-2213
    Dan Rosenberg discovered an issue in the INET socket
    monitoring interface. Local users could cause a denial
    of service by injecting code and causing the kernel to
    execute an infinite loop.

  - CVE-2011-2898
    Eric Dumazet reported an information leak in the raw
    packet socket implementation.

  - CVE-2011-3353
    Han-Wen Nienhuys reported a local denial of service
    issue in the FUSE (Filesystem in Userspace) support in
    the Linux kernel. Local users could cause a buffer
    overflow, leading to a kernel oops and resulting in a
    denial of service.

  - CVE-2011-4077
    Carlos Maiolino reported an issue in the XFS filesystem.
    A local user with the ability to mount a filesystem
    could corrupt memory resulting in a denial of service or
    possibly gain elevated privileges.

  - CVE-2011-4110
    David Howells reported an issue in the kernel's access
    key retention system which allow local users to cause a
    kernel oops leading to a denial of service.

  - CVE-2011-4127
    Paolo Bonzini of Red Hat reported an issue in the ioctl
    passthrough support for SCSI devices. Users with
    permission to access restricted portions of a device
    (e.g. a partition or a logical volume) can obtain access
    to the entire device by way of the SG_IO ioctl. This
    could be exploited by a local user or privileged VM
    guest to achieve a privilege escalation.

  - CVE-2011-4611
    Maynard Johnson reported an issue with the perf support
    on POWER7 systems that allows local users to cause a
    denial of service.

  - CVE-2011-4622
    Jan Kiszka reported an issue in the KVM PIT timer
    support. Local users with the permission to use KVM can
    cause a denial of service by starting a PIT timer
    without first setting up the irqchip.

  - CVE-2011-4914
    Ben Hutchings reported various bounds checking issues
    within the ROSE protocol support in the kernel. Remote
    users could possibly use this to gain access to
    sensitive memory or cause a denial of service."

    descriptionDescription of changes: * CVE-2011-2898: Information leak in packet subsystem Uninitialized struct padding in the packet subsystem led to an information leak of two bytes of kernel memory to userspace. * CVE-2011-2723: Remote denial of service vulnerability in gro. The skb_gro_header_slow function in the Linux kernel had a bug which allowed a remote attacker to put certain gro fields in an inconsistent state, resulting in a denial of service. * CVE-2011-2496: Local denial of service in mremap(). Robert Swiecki discovered that mremap() could be abused for local denial of service by triggering a BUG_ON assert. * CVE-2011-2484: Denial of service in taskstats subsystem. The add_del_listener function in kernel/taskstats.c in the Linux kernel did not prevent multiple registrations of exit handlers, which allowed local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application. * CVE-2011-1833: Information disclosure in eCryptfs. Vasiliy Kulikov of Openwall and Dan Rosenberg discovered that eCryptfs incorrectly validated permissions on the requested source directory. A local attacker could use this flaw to mount an arbitrary directory, possibly leading to information disclosure.

    descriptionUpdated kernel-rt packages that fix several security issues and two bugs are now available for Red Hat Enterprise MRG 2.0. 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. The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A malicious CIFS (Common Internet File System) server could send a specially crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted. (CVE-2011-3191, Important) * The way fragmented IPv6 UDP datagrams over the bridge with UDP Fragmentation Offload (UFO) functionality on were handled could allow a remote attacker to cause a denial of service. (CVE-2011-4326, Important) * GRO (Generic Receive Offload) fields could be left in an inconsistent state. An attacker on the local network could use this flaw to cause a denial of service. GRO is enabled by default in all network drivers that support it. (CVE-2011-2723, Moderate) * IPv4 and IPv6 protocol sequence number and fragment ID generation could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random. (CVE-2011-3188, Moderate) * A flaw in the FUSE (Filesystem in Userspace) implementation could allow a local user in the fuse group who has access to mount a FUSE file system to cause a denial of service. (CVE-2011-3353, Moderate) * A flaw in the b43 driver. If a system had an active wireless interface that uses the b43 driver, an attacker able to send a specially crafted frame to that interface could cause a denial of service. (CVE-2011-3359, Moderate) * A flaw in the way CIFS shares with DFS referrals at their root were handled could allow an attacker on the local network, who is able to deploy a malicious CIFS server, to create a CIFS network share that, when mounted, would cause the client system to crash. (CVE-2011-3363, Moderate) * A flaw in the m_stop() implementation could allow a local, unprivileged user to trigger a denial of service. (CVE-2011-3637, Moderate) * Flaws in ghash_update() and ghash_final() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-4081, Moderate) * A flaw in the key management facility could allow a local, unprivileged user to cause a denial of service via the keyctl utility. (CVE-2011-4110, Moderate) * A flaw in the Journaling Block Device (JBD) could allow a local attacker to crash the system by mounting a specially crafted ext3 or ext4 disk. (CVE-2011-4132, Moderate) * A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command. (CVE-2011-1162, Low) * I/O statistics from the taskstats subsystem could be read without any restrictions, which could allow a local, unprivileged user to gather confidential information, such as the length of a password used in a process. (CVE-2011-2494, Low) * Flaws in tpacket_rcv() and packet_recvmsg() could allow a local, unprivileged user to leak information to user-space. (CVE-2011-2898, Low) Red Hat would like to thank Darren Lavender for reporting CVE-2011-3191; Brent Meshier for reporting CVE-2011-2723; Dan Kaminsky for reporting CVE-2011-3188; Yogesh Sharma for reporting CVE-2011-3363; Nick Bowler for reporting CVE-2011-4081; Peter Huewe for reporting CVE-2011-1162; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2494. This update also fixes the following bugs : * Previously, a mismatch in the build-id of the kernel-rt and the one in the related debuginfo package caused failures in SystemTap and perf. (BZ#768413) * IBM x3650m3 systems were not able to boot the MRG Realtime kernel because they require a pmcraid driver that was not available. The pmcraid driver is included in this update. (BZ#753992) Users should upgrade to these updated packages, which correct these issues. The system must be rebooted for this update to take effect.
