CWE CWE-119
CAPEC
  • 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 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.

    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.

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-3503.NASL
    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service, information leak or data loss. - CVE-2013-4312, CVE-2016-2847 Tetsuo Handa discovered that users can use pipes queued on local (Unix) sockets to allocate an unfair share of kernel memory, leading to denial-of-service (resource exhaustion). This issue was previously mitigated for the stable suite by limiting the total number of files queued by each user on local sockets. The new kernel version in both suites includes that mitigation plus limits on the total size of pipe buffers allocated for each user. - CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected. - CVE-2015-8767 An SCTP denial-of-service was discovered which can be triggered by a local attacker during a heartbeat timeout event after the 4-way handshake. - CVE-2015-8785 It was discovered that local users permitted to write to a file on a FUSE filesystem could cause a denial of service (unkillable loop in the kernel). - CVE-2015-8812 A flaw was found in the iw_cxgb3 Infiniband driver. Whenever it could not send a packet because the network was congested, it would free the packet buffer but later attempt to send the packet again. This use-after-free could result in a denial of service (crash or hang), data loss or privilege escalation. - CVE-2015-8816 A use-after-free vulnerability was discovered in the USB hub driver. This may be used by a physically present user for privilege escalation. - CVE-2015-8830 Ben Hawkes of Google Project Zero reported that the AIO interface permitted reading or writing 2 GiB of data or more in a single chunk, which could lead to an integer overflow when applied to certain filesystems, socket or device types. The full security impact has not been evaluated. - CVE-2016-0723 A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial-of-service. - CVE-2016-0774 It was found that the fix for CVE-2015-1805 in kernel versions older than Linux 3.16 did not correctly handle the case of a partially failed atomic read. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space. - CVE-2016-2069 Andy Lutomirski discovered a race condition in flushing of the TLB when switching tasks on an x86 system. On an SMP system this could possibly lead to a crash, information leak or privilege escalation. - CVE-2016-2384 Andrey Konovalov found that a crafted USB MIDI device with an invalid USB descriptor could trigger a double-free. This may be used by a physically present user for privilege escalation. - CVE-2016-2543 Dmitry Vyukov found that the core sound sequencer driver (snd-seq) lacked a necessary check for a NULL pointer, allowing a user with access to a sound sequencer device to cause a denial-of service (crash). - CVE-2016-2544, CVE-2016-2546, CVE-2016-2547, CVE-2016-2548 Dmitry Vyukov found various race conditions in the sound subsystem (ALSA)'s management of timers. A user with access to sound devices could use these to cause a denial-of-service (crash or hang) or possibly for privilege escalation. - CVE-2016-2545 Dmitry Vyukov found a flaw in list manipulation in the sound subsystem (ALSA)'s management of timers. A user with access to sound devices could use this to cause a denial-of-service (crash or hang) or possibly for privilege escalation. - CVE-2016-2549 Dmitry Vyukov found a potential deadlock in the sound subsystem (ALSA)'s use of high resolution timers. A user with access to sound devices could use this to cause a denial-of-service (hang). - CVE-2016-2550 The original mitigation of CVE-2013-4312, limiting the total number of files a user could queue on local sockets, was flawed. A user given a local socket opened by another user, for example through the systemd socket activation mechanism, could make use of the other user's quota, again leading to a denial-of-service (resource exhaustion). This is fixed by accounting queued files to the sender rather than the socket opener.

    description The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c. (CVE-2013-4312) A race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel through 4.4.1 was found that allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call. (CVE-2016-0723) A privilege-escalation vulnerability was discovered in the Linux kernel built with User Namespace (CONFIG_USER_NS) support. The flaw occurred when the ptrace() system call was used on a root-owned process to enter a user namespace. A privileged namespace user could exploit this flaw to potentially escalate their privileges on the system, outside the original namespace. (CVE-2015-8709) net/sctp/sm_sideeffect.c in the Linux kernel before 4.3 does not properly manage the relationship between a lock and a socket, which allows local users to cause a denial of service (deadlock) via a crafted sctp_accept call.

    description 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) Notes : - Problems have been reported with this kernel and VirtualBox.

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.
