Summary

An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. Safari before 10.1.1 is affected. tvOS before 10.2.1 is affected. The issue involves the "JavaScriptCore" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

Common Attack Pattern Enumeration and Classification (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.

"According to its banner, the version of Apple TV on the remote device
is prior to 10.2.1. It is, therefore, affected by multiple
vulnerabilities :

  - A memory corruption issue exists in the WebKit Web
    Inspector component that allows an unauthenticated,
    remote attacker to execute arbitrary code.
    (CVE-2017-2499)

  - An unspecified race condition exists in the Kernel
    component that allows a local attacker to execute
    arbitrary code with kernel-level privileges.
    (CVE-2017-2501)

  - An information disclosure vulnerability exists in the
    CoreAudio component due to improper sanitization of
    certain input. A local attacker can exploit this to read
    the contents of restricted memory. (CVE-2017-2502)

  - A universal cross-site scripting (XSS) vulnerability
    exists in WebKit due to a logic flaw when handling
    WebKit Editor commands. An unauthenticated, remote
    attacker can exploit this, via a specially crafted web
    page, to execute arbitrary script code in a user's
    browser session. (CVE-2017-2504)

  - Multiple memory corruption issues exist in WebKit due to
    improper validation of certain input. An
    unauthenticated, remote attacker can exploit these to
    execute arbitrary code. (CVE-2017-2505, CVE-2017-2515,
    CVE-2017-2521, CVE-2017-2530, CVE-2017-2531,
    CVE-2017-6980, CVE-2017-6984)

  - Multiple information disclosure vulnerabilities exist
    in the Kernel component due to improper sanitization of
    certain input. A local attacker can exploit these to
    read the contents of restricted memory. (CVE-2017-2507,
    CVE-2017-6987)

  - A use-after-free error exists in the SQLite component
    when handling SQL queries. An unauthenticated, remote
    attacker can exploit this to deference already freed
    memory, resulting in the execution of arbitrary code.
    (CVE-2017-2513)

  - Multiple buffer overflow conditions exist in the SQLite
    component due to the improper validation of certain
    input. An unauthenticated, remote attacker can exploit
    these, via a specially crafted SQL query, to execute
    arbitrary code. (CVE-2017-2518, CVE-2017-2520)

  - A memory corruption issue exists in the SQLite component
    when handling SQL queries. An unauthenticated, remote
    attacker can exploit this, via a specially crafted
    query, to execute arbitrary code. (CVE-2017-2519)

  - An unspecified memory corruption issue exists in the
    TextInput component when parsing specially crafted data.
    An unauthenticated, remote attacker can exploit this to
    execute arbitrary code. (CVE-2017-2524)

  - A use-after-free error exists in WebKit when handling
    RenderLayer objects. An unauthenticated, remote attacker
    can exploit this, via a specially crafted web page, to
    deference already freed memory, resulting in the
    execution of arbitrary code. (CVE-2017-2525)

  - Multiple unspecified flaws exist in WebKit that allow
    an unauthenticated, remote attacker to corrupt memory
    and execute arbitrary code by using specially crafted
    web content. (CVE-2017-2536)

  - A universal cross-site scripting (XSS) vulnerability
    exists in WebKit due to a logic error when handling
    frame loading. An unauthenticated, remote attacker can
    exploit this, via a specially crafted web page, to
    execute arbitrary code in a user's browser session.
    (CVE-2017-2549)

  - An unspecified flaw exists in the IOSurface component
    that allows a local attacker to corrupt memory and
    execute arbitrary code with kernel-level privileges.
    (CVE-2017-6979)

  - An unspecified flaw exists in the AVEVideoEncoder
    component that allows a local attacker, via a specially
    crafted application, to corrupt memory and execute
    arbitrary code with kernel-level privileges.
    (CVE-2017-6989)

  - A denial of service vulnerability exists in the
    CoreText component due to improper validation of
    user-supplied input. An unauthenticated, remote attacker
    can exploit this, via a specially crafted file, to crash
    an application. (CVE-2017-7003)

  - A memory corruption issue exists in the JavaScriptCore
    component due to improper validation of user-supplied
    input. An unauthenticated, remote attacker can exploit
    this, via specially crafted web content, to cause a
    denial of service condition or the execution of
    arbitrary code. (CVE-2017-7005)
