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 Matthieu Herrb reports : Tobias Stoeckmann from the OpenBSD project has discovered a number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues. These issue come in addition to the ones discovered by Ilja van Sprundel in 2013. Most of these issues stem from the client libraries trusting the server to send correct protocol data, and not verifying that the values will not overflow or cause other damage. Most of the time X clients and servers are run by the same user, with the server more privileged than the clients, so this is not a problem, but there are scenarios in which a privileged client can be connected to an unprivileged server, for instance, connecting a setuid X client (such as a screen lock program) to a virtual X server (such as Xvfb or Xephyr) which the user has modified to return invalid data, potentially allowing the user to escalate their privileges.

An unauthenticated, remote attacker can exploit this, via a crafted DTLS message, to exhaust available memory resources. (CVE-2016-6308) - A flaw exists in Apache Tomcat within SecurityManager due to improper restriction of access to system properties by the configuration files system property replacement feature. A local attacker can exploit this, via a crafted web application, to bypass SecurityManager restrictions and disclose system properties. (CVE-2016-6794) - A flaw exists in Apache Tomcat that allows a local attacker to bypass a configured SecurityManager by changing the configuration parameters for the JSP Servlet. (CVE-2016-6796) - A flaw exists in Apache Tomcat due to a failure to limit web application access to global JNDI resources. A local attacker can exploit this to gain unauthorized access to resources. (CVE-2016-6797) - A flaw exists in Apache Tomcat when handling request lines containing certain invalid characters. An unauthenticated, remote attacker can exploit this to conduct HTTP response splitting attacks by injecting additional headers into responses. (CVE-2016-6816) - An infinite loop condition exists in Apache Tomcat in the HTTP/2 parser when handling overly large headers. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to cause a denial of service condition. (CVE-2016-6817) - A carry propagation error exists in the Broadwell-specific Montgomery multiplication procedure when handling input lengths divisible by but longer than 256 bits. This can result in transient authentication and key negotiation failures or reproducible erroneous outcomes of public-key operations with specially crafted input. A man-in-the-middle attacker can possibly exploit this issue to compromise ECDH key negotiations that utilize Brainpool P-512 curves. (CVE-2016-7055) - A flaw exists in cURL in the Curl_cookie_init() function within file lib/cookie.c when handling cookies. An unauthenticated, remote attacker can exploit this to inject new cookies for arbitrary domains. (CVE-2016-8615) - A flaw exists in cURL in the ConnectionExists() function within file lib/url.c when checking credentials supplied for reused connections due to the comparison being case-insensitive. An unauthenticated, remote attacker can exploit this to authenticate without knowing the proper case of the username and password. (CVE-2016-8616) - An integer overflow condition exists in cURL in the base64_encode() function within file lib/base64.c due to improper validation of certain input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-8617) - A denial of service vulnerability exists in cURL in the alloc_addbyter() function within file lib/mprintf.c due to improper validation of overly long input when it is supplied to the curl_maprintf() API method. An unauthenticated, remote attacker can exploit this to free already freed memory and thereby crash the program. (CVE-2016-8618) - A double-free error exists in cURL in the read_data() function within file lib/security.c when handling Kerberos authentication. An unauthenticated, remote attacker can exploit this to free already freed memory, resulting in an unspecified impact on confidentiality, integrity, and availability. (CVE-2016-8619) - An out-of-bounds access error exists in cURL in file tool_urlglob.c within the globbing feature. An unauthenticated, remote attacker can exploit this to disclose memory contents or execute arbitrary code. (CVE-2016-8620) - An out-of-bounds error exists in cURL in the parsedate() function within file lib/parsedate.c when handling dates. An unauthenticated, remote attacker can exploit this to disclose memory contents or cause a denial of service condition. (CVE-2016-8621) - An integer truncation error exists in cURL in the curl_easy_unescape() function within file lib/escape.c when handling overly large URLs. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-8622) - A use-after-free error exists in cURL within file lib/cookie.c when handling shared cookies. An unauthenticated, remote attacker can exploit this to disclose memory contents. (CVE-2016-8623) - A flaw exists in cURL in the parseurlandfillconn() function within file lib/url.c when parsing the authority component of a URL with the host name part ending in a '#' character. An unauthenticated, remote attacker can exploit this to establish a connection to a different host than intended. (CVE-2016-8624) - A flaw exists in cURL within International Domain Names (IDNA) handling when translating domain names to puny code for DNS resolving due to using the outdated IDNA 2003 standard instead of the IDNA 2008 standard, which can result in incorrect translation of a domain name. An unauthenticated, remote attacker can exploit this to cause network traffic to be redirected to a different host than intended. (CVE-2016-8625) - A flaw exists in Apache Tomcat within the catalina/mbeans/JmxRemoteLifecycleListener.java class that is triggered during the deserialization of Java objects. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-8735) - A flaw exists in the Web Server component (Apache HTTP Server) when handling whitespace patterns in User-Agent headers. An authenticated, remote attacker can exploit this, via a specially crafted User-Agent header, to cause incorrect processing of sequences of requests, resulting in incorrectly interpreting responses, polluting the cache, or disclosing content from one request to a second downstream user-agent. (CVE-2016-8743) - A NULL pointer dereference flaw exists within file ssl/statem/statem_clnt.c when handling parameters for the DHE or ECDHE key exchanges. An unauthenticated, remote attacker can exploit this, via specially crafted parameters, to cause a denial of service condition. (CVE-2017-3730) - A out-of-bounds read error exists exists in the Core subcomponent, specifically in OpenSSL, when handling packets using the CHACHA20/POLY1305 or RC4-MD5 ciphers. An unauthenticated, remote attacker can exploit this, via specially crafted truncated packets, to cause a denial of service condition. (CVE-2017-3731) - A carry propagating error exists in the x86_64 Montgomery squaring implementation that may cause the BN_mod_exp() function to produce incorrect results. An unauthenticated, remote attacker with sufficient resources can exploit this to obtain sensitive information regarding private keys. Note that this issue is very similar to CVE-2015-3193. Moreover, the attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. For example, this can occur by default in OpenSSL DHE based SSL/TLS cipher suites. (CVE-2017-3732) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DLA-667.NASL
    description Tobias Stoeckmann from the OpenBSD project has discovered a number of issues in the way various X client libraries handle the responses they receive from servers. Insufficient validation of data from the X server can cause out of boundary memory and memory corruption in the libxv library. For Debian 7 'Wheezy', these problems have been fixed in version 2:1.0.7-1+deb7u2. We recommend that you upgrade your libxv packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
