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.

Olivier Fourdan from Red Hat has discovered a protocol handling issue in the way the X server code base handles the XkbSetGeometry request, where the server trusts the client to send valid string lengths. A malicious client with string lengths exceeding the request length can cause the server to copy adjacent memory data into the XKB structs. This data is then available to the client via the XkbGetGeometry request. This can lead to information disclosure issues, as well as possibly a denial of service if a similar request can cause the server to crash (CVE-2015-0255).

    description Andreas Cord-Landwehr reported an issue where the X.Org Xserver would often crash with an arithmetic exception when maximizing application windows. This issue (CVE-2015-3418) is a regression which got introduced by fixing CVE-2014-8092. The above referenced version of xorg-server in Debian squeeze-lts fixes this regression in the following way : The length checking code validates PutImage height and byte width by making sure that byte-width >= INT32_MAX / height. If height is zero, this generates a divide by zero exception. Allow zero height requests explicitly, bypassing the INT32_MAX check (in dix/dispatch.c).

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description Ilja van Sprundel discovered a multitude of security issues in the X.Org X server. An attacker able to connect to an X server, either locally or remotely, could use these issues to cause the X server to crash or execute arbitrary code resulting in possible privilege escalation. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description Alan Coopersmith reports : Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way the X server code base handles requests from X clients, and has worked with X.Org's security team to analyze, confirm, and fix these issues. The vulnerabilities could be exploited to cause the X server to access uninitialized memory or overwrite arbitrary memory in the X server process. This can cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution. The GLX extension to the X Window System allows an X client to send X protocol to the X server, to request that the X server perform OpenGL rendering on behalf of the X client. This is known as 'GLX indirect rendering', as opposed to 'GLX direct rendering' where the X client submits OpenGL rendering commands directly to the GPU, bypassing the X server and avoiding the X server code for GLX protocol handling. Most GLX indirect rendering implementations share some common ancestry, dating back to 'Sample Implementation' code from Silicon Graphics, Inc (SGI), which SGI originally commercially licensed to other Unix workstation and graphics vendors, and later released as open source, so those vulnerabilities may affect other licensees of SGI's code base beyond those running code from the X.Org Foundation or the XFree86 Project.
