Summary

An issue was discovered in certain Apple products. iOS before 10.3.3 is affected. macOS before 10.12.6 is affected. tvOS before 10.2.2 is affected. watchOS before 3.2.3 is affected. The issue involves the "Kernel" component. It allows attackers to bypass intended memory-read restrictions via a crafted app.

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.

descriptionThe remote host is running Mac OS X 10.10.5, Mac OS X 10.11.6, or macOS 10.12.5 and is missing a security update. It is therefore, affected by multiple vulnerabilities : - An overflow condition exists in the curl component in the dprintf_formatf() function that is triggered when handling floating point conversion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9586) - A flaw exits in the curl component in the randit() function within file lib/rand.c due to improper initialization of the 32-bit random value, which is used, for example, to generate Digest and NTLM authentication nonces, resulting in weaker cryptographic operations than expected. (CVE-2016-9594) - A flaw exists in the curl component in the allocate_conn() function in lib/url.c when using the OCSP stapling feature for checking a X.509 certificate revocation status. The issue is triggered as the request option for OCSP stapling is not properly passed to the TLS library, resulting in no error being returned even when no proof of the validity of the certificate could be provided. A man-in-the-middle attacker can exploit this to provide a revoked certificate. (CVE-2017-2629) - A remote code execution vulnerability exists in the CoreAudio component due to improper validation of user-supplied input when handling movie files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted movie file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7008) - A memory corruption issue exists in the IOUSBFamily component due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7009) - Multiple out-of-bounds read errors exist in the libxml2 component due to improper handling of specially crafted XML documents. An unauthenticated, remote attacker can exploit these to disclose user information. (CVE-2017-7010, CVE-2017-7013) - Multiple memory corruption issues exist in the Intel Graphics Driver component due to improper validation of input. A local attacker can exploit these issues to execute arbitrary code with elevated privileges. (CVE-2017-7014, CVE-2017-7017, CVE-2017-7035, CVE-2017-7044) - A remote code execution vulnerability exists in the Audio component due to improper validation of user-supplied input when handling audio files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted audio file, to execute arbitrary code. (CVE-2017-7015) - Multiple remote code execution vulnerabilities exist in the afclip component due to improper validation of user-supplied input when handling audio files. An unauthenticated, remote attacker can exploit these vulnerabilities, by convincing a user to play a specially crafted audio file, to execute arbitrary code. (CVE-2017-7016, CVE-2017-7033) - A memory corruption issue exists in the AppleGraphicsPowerManagement component due to improper validation of input. A local attacker can exploit this to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7021) - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7022, CVE-2017-7024, CVE-2017-7026) - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with kernel privileges. (CVE-2017-7023, CVE-2017-7025, CVE-2017-7027, CVE-2017-7069) - Multiple unspecified flaws exist in the kernel due to a failure to properly sanitize input. A local attacker can exploit these issues, via a specially crafted application, to disclose restricted memory contents. (CVE-2017-7028, CVE-2017-7029, CVE-2017-7067) - A flaw exists in the Foundation component due to improper validation of input. A unauthenticated, remote attacker can exploit this, by convincing a user to open specially crafted file, to execute arbitrary code. (CVE-2017-7031) - A memory corruption issue exists in the
