Summary

The Microsoft Windows embedded OpenType (EOT) font engine in Windows 7 SP1, Windows Server 2008 SP2 and 2008 R2 SP1, and Windows Server 2012 allows an attacker to potentially read data that was not intended to be disclosed, due to the way that the Microsoft Windows EOT font engine parses specially crafted embedded fonts, aka "Windows EOT Font Engine Information Disclosure Vulnerability." This CVE ID is unique from CVE-2017-11835.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

"The remote Windows host is missing security update 4048962
or cumulative update 4048959. It is, therefore, affected by
multiple vulnerabilities :

  - An information disclosure vulnerability exists in the
    way that the Microsoft Windows Embedded OpenType (EOT)
    font engine parses specially crafted embedded fonts. An
    attacker who successfully exploited this vulnerability
    could potentially read data that was not intended to be
    disclosed. Note that this vulnerability would not allow
    an attacker to execute code or to elevate their user
    rights directly, but it could be used to obtain
    information that could be used to try to further
    compromise the affected system.  (CVE-2017-11832)

  - A remote code execution vulnerability exists in the way
    that Microsoft browsers access objects in memory. The
    vulnerability could corrupt memory in a way that could
    allow an attacker to execute arbitrary code in the
    context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2017-11827,
    CVE-2017-11858)

  - An information vulnerability exists when Windows Media
    Player improperly discloses file information. Successful
    exploitation of the vulnerability could allow the
    attacker to test for the presence of files on disk.
    (CVE-2017-11768)

  - An information disclosure vulnerability exists when the
    scripting engine does not properly handle objects in
    memory in Internet Explorer. An attacker who
    successfully exploited the vulnerability could obtain
    information to further compromise the users system.
    (CVE-2017-11834)

  - An information disclosure vulnerability exists when the
    Windows kernel improperly initializes objects in memory.
    (CVE-2017-11880)

  - A Win32k information disclosure vulnerability exists
    when the Windows GDI component improperly discloses
    kernel memory addresses. An attacker who successfully
    exploited the vulnerability could obtain information to
    further compromise the users system.  (CVE-2017-11851)

  - A remote code execution vulnerability exists when
    Internet Explorer improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that an attacker could execute arbitrary code in the
    context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2017-11855,
    CVE-2017-11869)

  - An information disclosure vulnerability exists when the
    scripting engine does not properly handle objects in
    memory in Microsoft browsers. An attacker who
    successfully exploited the vulnerability could obtain
    information to further compromise the users system.
    (CVE-2017-11791)

  - An elevation of privilege vulnerability exists when the
    Windows kernel fails to properly handle objects in
    memory. An attacker who successfully exploited this
    vulnerability could run arbitrary code in kernel mode.
    An attacker could then install programs; view, change,
    or delete data; or create new accounts with full user
    rights.  (CVE-2017-11847)

  - An information disclosure vulnerability exists when
    Internet Explorer improperly handles page content, which
    could allow an attacker to detect the navigation of the
    user leaving a maliciously crafted page.
    (CVE-2017-11848)

  - An information disclosure vulnerability exists when the
    Windows kernel fails to properly initialize a memory
    address. An attacker who successfully exploited this
    vulnerability could obtain information to further
    compromise the users system.  (CVE-2017-11831,
    CVE-2017-11842, CVE-2017-11849, CVE-2017-11853)

  - A denial of service vulnerability exists when Windows
    Search improperly handles objects in memory. An attacker
    who successfully exploited the vulnerability could cause
    a remote denial of service against a system.
    (CVE-2017-11788)

  - An information disclosure vulnerability exists when the
    Microsoft Windows Graphics Component improperly handles
    objects in memory. An attacker who successfully
    exploited the vulnerability could obtain information to
    further compromise the users system.  (CVE-2017-11850)

  - A remote code execution vulnerability exists in the way
    the scripting engine handles objects in memory in
    Microsoft browsers. The vulnerability could corrupt
    memory in such a way that an attacker could execute
    arbitrary code in the context of the current user. An
    attacker who successfully exploited the vulnerability
    could gain the same user rights as the current user.
