  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation or denial of service. - CVE-2015-8215 It was discovered that NetworkManager would set IPv6 MTUs based on the values received in IPv6 RAs (Router Advertisements), without sufficiently validating these values. A remote attacker could exploit this attack to disable IPv6 connectivity. This has been mitigated by adding validation in the kernel. - CVE-2015-2925 Jann Horn discovered that when a subdirectory of a filesystem is bind-mounted into a container that has its own user and mount namespaces, a process with CAP_SYS_ADMIN capability in the user namespace can access files outside of the subdirectory. The default Debian configuration mitigated this as it does not allow unprivileged users to create new user namespaces. - CVE-2015-5156 Jason Wang discovered that when a virtio_net device is connected to a bridge in the same VM, a series of TCP packets forwarded through the bridge may cause a heap buffer overflow. A remote attacker could use this to cause a denial of service (crash) or possibly for privilege escalation. - CVE-2015-6252 Michael S. Tsirkin of Red Hat Engineering found that the vhost driver leaked file descriptors passed to it with the VHOST_SET_LOG_FD ioctl command. A privileged local user with access to the /dev/vhost-net file, either directly or via libvirt, could use this to cause a denial of service (hang or crash). - CVE-2015-6937 It was found that the Reliable Datagram Sockets (RDS) protocol implementation did not verify that an underlying transport exists when creating a connection. Depending on how a local RDS application initialised its sockets, a remote attacker might be able to cause a denial of service (crash) by sending a crafted packet. - CVE-2015-7312 Xavier Chantry discovered that the patch provided by the aufs project to correct behaviour of memory-mapped files from an aufs mount introduced a race condition in the msync() system call. Ben Hutchings found that it also introduced a similar bug in the madvise_remove() function. A local attacker could use this to cause a denial of service or possibly for privilege escalation.

    description From Red Hat Security Advisory 2016:0855 : An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * It was found that reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mapped to userspace as part of vdso (vvar) and thus an unprivileged user may generate MMIO transactions (and enter the emulator) this way. (CVE-2010-5313, CVE-2014-7842, Moderate) * It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system. (CVE-2013-4312, Moderate) * A buffer overflow flaw was found in the way the Linux kernel's virtio-net subsystem handled certain fraglists when the GRO (Generic Receive Offload) functionality was enabled in a bridged network configuration. An attacker on the local network could potentially use this flaw to crash the system, or, although unlikely, elevate their privileges on the system. (CVE-2015-5156, Moderate) * It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system. (CVE-2015-8215, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system. (CVE-2015-8543, Moderate) * It was found that the espfix functionality does not work for 32-bit KVM paravirtualized guests. A local, unprivileged guest user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8134, Low) * A flaw was found in the way the Linux kernel's ext4 file system driver handled non-journal file systems with an orphan list. An attacker with physical access to the system could use this flaw to crash the system or, although unlikely, escalate their privileges on the system. (CVE-2015-7509, Low) * A NULL pointer dereference flaw was found in the way the Linux kernel's ext4 file system driver handled certain corrupted file system images. An attacker with physical access to the system could use this flaw to crash the system. (CVE-2015-8324, Low) Red Hat would like to thank Nadav Amit for reporting CVE-2010-5313 and CVE-2014-7842, Andy Lutomirski for reporting CVE-2014-8134, and Dmitriy Monakhov (OpenVZ) for reporting CVE-2015-8324. The CVE-2015-5156 issue was discovered by Jason Wang (Red Hat).

    NASL id SUSE_SU-2015-1727-1.NASL
    description The SUSE Linux Enterprise 12 kernel was updated to 3.12.48-52.27 to receive various security and bugfixes. Following security bugs were fixed : - CVE-2015-7613: A flaw was found in the Linux kernel IPC code that could lead to arbitrary code execution. The ipc_addid() function initialized a shared object that has unset uid/gid values. Since the fields are not initialized, the check can falsely succeed. (bsc#948536) - CVE-2015-5156: When a guests KVM network devices is in a bridge configuration the kernel can create a situation in which packets are fragmented in an unexpected fashion. The GRO functionality can create a situation in which multiple SKB's are chained together in a single packets fraglist (by design). (bsc#940776) - CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform mishandles IRET faults in processing NMIs that occurred during userspace execution, which might allow local users to gain privileges by triggering an NMI (bsc#938706). - CVE-2015-6252: A flaw was found in the way the Linux kernel's vhost driver treated userspace provided log file descriptor when processing the VHOST_SET_LOG_FD ioctl command. The file descriptor was never released and continued to consume kernel memory. A privileged local user with access to the /dev/vhost-net files could use this flaw to create a denial-of-service attack (bsc#942367). - CVE-2015-5697: The get_bitmap_file function in drivers/md/md.c in the Linux kernel before 4.1.6 does not initialize a certain bitmap data structure, which allows local users to obtain sensitive information from kernel memory via a GET_BITMAP_FILE ioctl call. (bnc#939994) - CVE-2015-6937: A NULL pointer dereference flaw was found in the Reliable Datagram Sockets (RDS) implementation allowing a local user to cause system DoS. A verification was missing that the underlying transport exists when a connection was created. (bsc#945825) - CVE-2015-5283: A NULL pointer dereference flaw was found in SCTP implementation allowing a local user to cause system DoS. Creation of multiple sockets in parallel when system doesn't have SCTP module loaded can lead to kernel panic. (bsc#947155) The following non-security bugs were fixed : - ALSA: hda - Abort the probe without i915 binding for HSW/BDW (bsc#936556). - Btrfs: Backport subvolume mount option handling (bsc#934962) -

  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2016-0855.NASL
    description An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * It was found that reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mapped to userspace as part of vdso (vvar) and thus an unprivileged user may generate MMIO transactions (and enter the emulator) this way. (CVE-2010-5313, CVE-2014-7842, Moderate) * It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system. (CVE-2013-4312, Moderate) * A buffer overflow flaw was found in the way the Linux kernel's virtio-net subsystem handled certain fraglists when the GRO (Generic Receive Offload) functionality was enabled in a bridged network configuration. An attacker on the local network could potentially use this flaw to crash the system, or, although unlikely, elevate their privileges on the system. (CVE-2015-5156, Moderate) * It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system. (CVE-2015-8215, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system. (CVE-2015-8543, Moderate) * It was found that the espfix functionality does not work for 32-bit KVM paravirtualized guests. A local, unprivileged guest user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8134, Low) * A flaw was found in the way the Linux kernel's ext4 file system driver handled non-journal file systems with an orphan list. An attacker with physical access to the system could use this flaw to crash the system or, although unlikely, escalate their privileges on the system. (CVE-2015-7509, Low) * A NULL pointer dereference flaw was found in the way the Linux kernel's ext4 file system driver handled certain corrupted file system images. An attacker with physical access to the system could use this flaw to crash the system. (CVE-2015-8324, Low) Red Hat would like to thank Nadav Amit for reporting CVE-2010-5313 and CVE-2014-7842, Andy Lutomirski for reporting CVE-2014-8134, and Dmitriy Monakhov (OpenVZ) for reporting CVE-2015-8324. The CVE-2015-5156 issue was discovered by Jason Wang (Red Hat). Additional Changes : * Refer to Red Hat Enterprise Linux 6.8 Release Notes for information on new kernel features and known issues, and Red Hat Enterprise Linux Technical Notes for information on device driver updates, important changes to external kernel parameters, notable bug fixes, and technology previews. Both of these documents are linked to in the References section.

    description It was discovered that virtio networking in the Linux kernel did not handle fragments correctly, leading to kernel memory corruption. A remote attacker could use this to cause a denial of service (system crash) or possibly execute code with administrative privileges. (CVE-2015-5156) Benjamin Randazzo discovered an information leak in the md (multiple device) driver when the bitmap_info.file is disabled. A local privileged attacker could use this to obtain sensitive information from the kernel. (CVE-2015-5697) Marc-Andre Lureau discovered that the vhost driver did not properly release the userspace provided log file descriptor. A privileged attacker could use this to cause a denial of service (resource exhaustion). (CVE-2015-6252) It was discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel did not verify sockets were properly bound before attempting to send a message, which could cause a NULL pointer dereference. An attacker could use this to cause a denial of service (system crash). (CVE-2015-6937) Ben Hutchings discovered that the Advanced Union Filesystem (aufs) for the Linux kernel did not correctly handle references of memory mapped files from an aufs mount.

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DLA-310.NASL
    description This update fixes the CVEs described below. CVE-2015-0272 It was discovered that NetworkManager would set IPv6 MTUs based on the values received in IPv6 RAs (Router Advertisements), without sufficiently validating these values. A remote attacker could exploit this attack to disable IPv6 connectivity. This has been mitigated by adding validation in the kernel. CVE-2015-5156 Jason Wang discovered that when a virtio_net device is connected to a bridge in the same VM, a series of TCP packets forwarded through the bridge may cause a heap buffer overflow. A remote attacker could use this to cause a denial of service (crash) or possibly for privilege escalation. CVE-2015-5364 It was discovered that the Linux kernel does not properly handle invalid UDP checksums. A remote attacker could exploit this flaw to cause a denial of service using a flood of UDP packets with invalid checksums. CVE-2015-5366 It was discovered that the Linux kernel does not properly handle invalid UDP checksums. A remote attacker can cause a denial of service against applications that use epoll by injecting a single packet with an invalid checksum. CVE-2015-5697 A flaw was discovered in the md driver in the Linux kernel leading to an information leak. CVE-2015-5707 An integer overflow in the SCSI generic driver in the Linux kernel was discovered. A local user with write permission on a SCSI generic device could potentially exploit this flaw for privilege escalation. CVE-2015-6937 It was found that the Reliable Datagram Sockets (RDS) protocol implementation did not verify that an underlying transport exists when creating a connection. Depending on how a local RDS application initialised its sockets, a remote attacker might be able to cause a denial of service (crash) by sending a crafted packet. For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze14. For the oldstable distribution (wheezy), these problems have been fixed in version 3.2.68-1+deb7u4 or earlier. For the stable distribution (jessie), these problems have been fixed in version 3.16.7-ckt11-1+deb8u4 or earlier.

    title Oracle Linux 5 / 6 : Unbreakable Enterprise kernel (ELSA-2015-3093)
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2016-0855.NASL
    description An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * It was found that reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mapped to userspace as part of vdso (vvar) and thus an unprivileged user may generate MMIO transactions (and enter the emulator) this way. (CVE-2010-5313, CVE-2014-7842, Moderate) * It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system. (CVE-2013-4312, Moderate) * A buffer overflow flaw was found in the way the Linux kernel's virtio-net subsystem handled certain fraglists when the GRO (Generic Receive Offload) functionality was enabled in a bridged network configuration. An attacker on the local network could potentially use this flaw to crash the system, or, although unlikely, elevate their privileges on the system. (CVE-2015-5156, Moderate) * It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system. (CVE-2015-8215, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system. (CVE-2015-8543, Moderate) * It was found that the espfix functionality does not work for 32-bit KVM paravirtualized guests. A local, unprivileged guest user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8134, Low) * A flaw was found in the way the Linux kernel's ext4 file system driver handled non-journal file systems with an orphan list. An attacker with physical access to the system could use this flaw to crash the system or, although unlikely, escalate their privileges on the system. (CVE-2015-7509, Low) * A NULL pointer dereference flaw was found in the way the Linux kernel's ext4 file system driver handled certain corrupted file system images. An attacker with physical access to the system could use this flaw to crash the system. (CVE-2015-8324, Low) Red Hat would like to thank Nadav Amit for reporting CVE-2010-5313 and CVE-2014-7842, Andy Lutomirski for reporting CVE-2014-8134, and Dmitriy Monakhov (OpenVZ) for reporting CVE-2015-8324. The CVE-2015-5156 issue was discovered by Jason Wang (Red Hat). Additional Changes : * Refer to Red Hat Enterprise Linux 6.8 Release Notes for information on new kernel features and known issues, and Red Hat Enterprise Linux Technical Notes for information on device driver updates, important changes to external kernel parameters, notable bug fixes, and technology previews. Both of these documents are linked to in the References section.
