CVE-2023-41064 is a buffer overflow vulnerability classified under CWE-120 that affects Apple macOS and related operating systems including iOS and iPadOS. The vulnerability stems from improper memory handling when processing specially crafted image files, which can lead to arbitrary code execution. This means an attacker can execute malicious code on a vulnerable system by convincing a user to open or process a malicious image, potentially compromising the system's confidentiality, integrity, and availability. The vulnerability requires user interaction but no prior authentication, increasing its risk profile. Apple has addressed this issue by improving memory handling in the affected components and released patches across multiple OS versions: macOS Monterey 12.6.9, Ventura 13.5.2, Big Sur 11.7.10, iOS 16.6.1, iPadOS 16.6.1, and earlier supported versions. The CVSS v3.1 base score is 7.8, reflecting high severity with attack vector local, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. While Apple has not confirmed active exploitation, it is aware of reports suggesting potential exploitation attempts, underscoring the urgency of patching. The vulnerability is particularly dangerous because image files are commonly shared and opened, making social engineering a likely attack vector. This vulnerability could be exploited to install malware, steal sensitive information, or disrupt system operations on Apple devices.

For European organizations, the impact of CVE-2023-41064 is significant due to the widespread use of Apple devices in both consumer and enterprise environments. Successful exploitation can lead to arbitrary code execution, allowing attackers to gain unauthorized access, execute malicious payloads, or disrupt critical services. This threatens the confidentiality of sensitive data, the integrity of systems and applications, and the availability of services. Sectors such as finance, healthcare, government, and critical infrastructure that rely on Apple devices for daily operations are particularly at risk. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious images, increasing the attack surface. Additionally, the vulnerability could be leveraged in targeted attacks against high-value European organizations or individuals. Failure to patch promptly may result in data breaches, operational disruptions, reputational damage, and regulatory penalties under GDPR and other data protection laws.

1. Immediately apply the security updates released by Apple for all affected operating systems, including macOS Monterey 12.6.9, Ventura 13.5.2, Big Sur 11.7.10, iOS 16.6.1, and iPadOS 16.6.1 or later versions. 2. Implement strict controls on the sources of image files, restricting downloads and email attachments to trusted origins only. 3. Educate users about the risks of opening unsolicited or unexpected image files, emphasizing caution with files received via email or messaging platforms. 4. Deploy endpoint detection and response (EDR) solutions capable of monitoring for anomalous behavior indicative of exploitation attempts related to image processing. 5. Use network-level protections such as email filtering and sandboxing to detect and block malicious image files before they reach end users. 6. Regularly audit and inventory Apple devices within the organization to ensure all are updated and compliant with security policies. 7. Monitor security advisories from Apple and threat intelligence sources for any emerging exploitation techniques or indicators of compromise related to this vulnerability. 8. Consider implementing application whitelisting or restricting execution privileges to limit the impact of potential code execution.
