CVE-2017-7013: An issue was discovered in certain Apple products.

An issue was discovered in certain Apple products. iOS before 10.3.3 is affected. macOS before 10.12.6 is affected. iCloud before 6.2.2 on Windows is affected. iTunes before 12.6.2 on Windows is affected. tvOS before 10.2.2 is affected. watchOS before 3.2.3 is affected. The issue involves the "libxml2" component. It allows remote attackers to obtain sensitive information or cause a denial of service (out-of-bounds read and application crash) via a crafted XML file.

Security readout for executives and security teams

Plain-English summary

This Apple vulnerability affects XML processing in several older Apple platforms and Windows Apple apps. A maliciously crafted XML file could expose sensitive information or crash an affected application. The bundle does not show active exploitation or a CVSS score.

Executive priority

Treat this as a legacy exposure cleanup item unless affected systems still process untrusted XML. It is not KEV-listed in the supplied data, but it can still cause data exposure or application outages on outdated systems.

Technical view

CVE-2017-7013 is an out-of-bounds read in Apple’s libxml2 component. A remote attacker could trigger information disclosure or denial of service by supplying crafted XML to affected products before the listed fixed versions.

Likely exposure

Exposure is mainly legacy Apple estates: iOS before 10.3.3, macOS before 10.12.6, tvOS before 10.2.2, watchOS before 3.2.3, iCloud for Windows before 6.2.2, and iTunes for Windows before 12.6.2.

Exploitation context

The source bundle does not identify active exploitation, and KEV is false. The stated attack path is a crafted XML file reaching the vulnerable libxml2 component in affected Apple software.

Researcher notes

The bundle lacks CVSS, CWE, and detailed Apple advisory text, so severity precision is limited. The useful evidence is the affected product/version list, libxml2 component, impact description, and absence of KEV evidence.

Mitigation direction

  • Update affected Apple products to the fixed versions or later named in the CVE bundle.
  • Prioritize systems that process XML from email, web, file shares, or untrusted applications.
  • Remove or isolate unsupported legacy Apple software that cannot be updated.
  • Check Apple security guidance for any product-specific update constraints.

Validation and detection

  • Inventory iOS, macOS, tvOS, watchOS, iCloud for Windows, and iTunes for Windows versions.
  • Confirm affected assets are at or above the fixed versions listed in the bundle.
  • Review crash and telemetry data for suspicious XML parsing failures.
  • Verify vulnerability scanners map findings to CVE-2017-7013 and the affected version ranges.
