CVE-2022-32841 is a medium severity vulnerability affecting Apple macOS and other Apple operating systems such as watchOS, tvOS, iOS, and iPadOS. The vulnerability arises from improper memory handling when processing a maliciously crafted image file. Specifically, the flaw is a type of out-of-bounds read (CWE-125), where the system may read beyond the intended memory buffer boundaries during image processing. This can lead to the unintended disclosure of process memory contents to an attacker. The vulnerability requires local access (attack vector: local) and user interaction, meaning the user must open or otherwise process the malicious image file for exploitation to occur. No privileges are required to exploit this vulnerability, but the attacker must trick the user into opening the crafted image. The impact is confidentiality loss due to disclosure of sensitive memory data, but there is no impact on integrity or availability. The vulnerability was addressed by Apple through improved memory handling and fixed in macOS Monterey 12.5, iOS 15.6, iPadOS 15.6, watchOS 8.7, and tvOS 15.6. There are no known exploits in the wild at the time of publication. The CVSS v3.1 base score is 5.5 (medium severity), reflecting the limited attack vector (local), requirement for user interaction, and the impact limited to confidentiality. This vulnerability is significant because image files are commonly shared and opened, and a malicious image could be embedded in emails, websites, or documents. However, exploitation requires user action and local access, which limits remote exploitation potential. The vulnerability affects all versions prior to the patched releases, but the exact affected versions are unspecified in the provided data. The vulnerability is relevant to all Apple device users running vulnerable OS versions, including macOS users in enterprise and personal environments.

For European organizations, the primary impact of CVE-2022-32841 is the potential leakage of sensitive process memory data on Apple devices. This could include confidential information such as cryptographic keys, passwords, or proprietary data residing in memory at the time of image processing. Although the vulnerability does not allow code execution or system compromise, the confidentiality breach could facilitate further attacks or data exfiltration. Organizations with a significant number of Apple devices, especially macOS endpoints, are at risk if users open malicious images. Sectors such as finance, government, healthcare, and technology in Europe, which often handle sensitive data, could be particularly impacted by such memory disclosures. The requirement for user interaction means that phishing or social engineering campaigns could be used to deliver the malicious images. Given the widespread use of Apple devices in European enterprises and public institutions, unpatched systems could expose sensitive internal data. However, the lack of known exploits and the medium severity rating suggest the threat is moderate but should not be ignored. Timely patching is critical to prevent potential data leaks and maintain compliance with data protection regulations such as GDPR.

European organizations should implement the following specific mitigation measures: 1) Prioritize patch management by deploying the fixed versions of macOS Monterey 12.5, iOS 15.6, iPadOS 15.6, watchOS 8.7, and tvOS 15.6 across all Apple devices in the environment. 2) Implement strict email and web filtering to detect and block potentially malicious image files, especially from untrusted sources. 3) Educate users on the risks of opening unsolicited or suspicious image files, emphasizing the importance of verifying the source before interacting with attachments or embedded images. 4) Employ endpoint detection and response (EDR) solutions capable of monitoring unusual memory access patterns or suspicious image processing activities on Apple devices. 5) Restrict local user privileges where possible to limit the impact of local attacks and reduce the likelihood of successful exploitation. 6) Conduct regular security audits and vulnerability assessments focused on Apple device fleets to ensure compliance with patching policies. 7) Utilize network segmentation to isolate critical systems and sensitive data from endpoints that may be exposed to user-driven attacks. These targeted actions go beyond generic advice by focusing on the specific attack vector (malicious image processing) and the affected platforms.
