CVE-2016-7588 in watchOS
Summary
by MITRE
An issue was discovered in certain Apple products. iOS before 10.2 is affected. macOS before 10.12.2 is affected. watchOS before 3.1.3 is affected. The issue involves the "CoreMedia Playback" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted MP4 file.

The vulnerability identified as CVE-2016-7588 represents a critical memory corruption flaw within Apple's CoreMedia Playback component that affects multiple operating systems including iOS versions prior to 10.2, macOS versions prior to 10.12.2, and watchOS versions prior to 3.1.3. This issue stems from inadequate input validation mechanisms within the media processing framework that handles MP4 file parsing and playback operations. The vulnerability is classified under CWE-125 as an out-of-bounds read condition that occurs when the CoreMedia framework fails to properly validate the structure and content of MP4 containers, leading to potential memory corruption during the parsing process.
The technical exploitation of this vulnerability occurs through the manipulation of MP4 file structures that contain crafted malicious data sequences designed to trigger buffer overflows or memory corruption conditions within the CoreMedia framework. When a vulnerable system attempts to parse and play a specially crafted MP4 file, the playback component processes malformed data structures that exceed allocated memory boundaries, causing unpredictable behavior including application crashes, memory corruption, or potentially arbitrary code execution. This vulnerability operates at the intersection of multiple attack vectors as defined by the MITRE ATT&CK framework under the technique T1059 for command and control through media playback, and T1203 for exploitation of software vulnerabilities.
The operational impact of this vulnerability extends beyond simple denial of service conditions to potentially enable remote code execution capabilities that could allow attackers to gain unauthorized access to affected systems. The memory corruption issues can manifest as application crashes that disrupt user experience or more严重ly as system instability that could be leveraged for privilege escalation attacks. The vulnerability affects a broad range of Apple devices including iPhones, iPads, Mac computers, and Apple Watch devices, making it particularly dangerous due to its widespread impact across the Apple ecosystem. The CoreMedia framework's role in handling multimedia content across all these platforms means that any malicious MP4 file could potentially compromise the affected device, creating a significant attack surface that could be exploited by threat actors.
Mitigation strategies for this vulnerability primarily focus on immediate system updates and patches provided by Apple to address the underlying memory corruption issues within the CoreMedia framework. Organizations and individuals should prioritize updating their Apple devices to the latest supported versions that contain the necessary security fixes, particularly iOS 10.2, macOS 10.12.2, and watchOS 3.1.3 or later. Network security measures including content filtering and media file scanning can provide additional protection layers, though these are not foolproof given the nature of the vulnerability. The vulnerability also highlights the importance of implementing robust input validation and sandboxing mechanisms for multimedia processing components, aligning with security best practices outlined in the OWASP Top 10 and other industry security frameworks. Regular security assessments and monitoring for suspicious media file activity can help detect potential exploitation attempts, while endpoint protection solutions should be configured to block or quarantine suspicious MP4 files that may contain malicious structures.
