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 Updated qemu-kvm packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the user-space component for running virtual machines using KVM. An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-1714) Red Hat would like to thank Donghai Zhu of Alibaba for reporting this issue. This update also fixes the following bugs : * Incorrect handling of the last sector of an image file could trigger an assertion failure in qemu-img. This update changes the handling of the last sector, and no assertion failure occurs. (BZ#1298828) All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

    NASL id SL_20160128_QEMU_KVM_ON_SL7_X.NASL
    description An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-1714) This update also fixes the following bugs : - Incorrect handling of the last sector of an image file could trigger an assertion failure in qemu-img. This update changes the handling of the last sector, and no assertion failure occurs. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

    description From Red Hat Security Advisory 2016:0083 : Updated qemu-kvm packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the user-space component for running virtual machines using KVM. An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-1714) Red Hat would like to thank Donghai Zhu of Alibaba for reporting this issue. This update also fixes the following bugs : * Incorrect handling of the last sector of an image file could trigger an assertion failure in qemu-img. This update changes the handling of the last sector, and no assertion failure occurs. (BZ#1298828) All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-1714) Red Hat would like to thank Donghai Zhu of Alibaba for reporting this issue. All qemu-kvm users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

CVE-2016-4439: The esp_reg_write function in the 53C9X Fast SCSI Controller (FSC) support did not properly check command buffer length, which allowed local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the host via unspecified vectors (bsc#980716) - CVE-2016-3960: Integer overflow in the x86 shadow pagetable code allowed local guest OS users to cause a denial of service (host crash) or possibly gain privileges by shadowing a superpage mapping (bsc#974038) - CVE-2016-3158: The xrstor function did not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allowed local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits (bsc#973188) - CVE-2016-3159: The fpu_fxrstor function in arch/x86/i387.c did not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allowed local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits (bsc#973188) - CVE-2016-4037: The ehci_advance_state function in hw/usb/hcd-ehci.c allowed local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via a circular split isochronous transfer descriptor (siTD) list (bsc#976111) - CVE-2016-4020: The patch_instruction function did not initialize the imm32 variable, which allowed local guest OS administrators to obtain sensitive information from host stack memory by accessing the Task Priority Register (TPR) (bsc#975907) - CVE-2016-4001: Buffer overflow in the stellaris_enet_receive function, when the Stellaris ethernet controller is configured to accept large packets, allowed remote attackers to cause a denial of service (QEMU crash) via a large packet (bsc#975130) - CVE-2016-4002: Buffer overflow in the mipsnet_receive function, when the guest NIC is configured to accept large packets, allowed remote attackers to cause a denial of service (memory corruption and QEMU crash) or possibly execute arbitrary code via a packet larger than 1514 bytes (bsc#975138) - CVE-2016-4480: The guest_walk_tables function in arch/x86/mm/guest_walk.c in Xen did not properly handle the Page Size (PS) page table entry bit at the L4 and L3 page table levels, which might have allowed local guest OS users to gain privileges via a crafted mapping of memory (bsc#978295) These non-security issues were fixed : -
