CVE-2024-54500 is a vulnerability identified in Apple tvOS and other Apple operating systems such as iPadOS, watchOS, visionOS, macOS, and iOS. The vulnerability arises from improper handling of specially crafted image files, which when processed, can lead to disclosure of process memory. This memory disclosure can expose sensitive data residing in the process’s memory space, potentially including cryptographic keys, user data, or other confidential information. The vulnerability does not allow modification or disruption of system operations but compromises confidentiality. The flaw requires an attacker to have local privileges (AV:L - local access) and low attack complexity (AC:L), with no user interaction (UI:N) needed, making it a stealthy vector for information leakage. The vulnerability affects unspecified versions prior to the patched releases: iPadOS 17.7.3, watchOS 11.2, visionOS 2.2, tvOS 18.2, macOS Sequoia 15.2, iOS 18.2, macOS Ventura 13.7.2, and macOS Sonoma 14.7.2. Apple addressed the issue by implementing improved validation checks on image processing routines to prevent memory disclosure. No known exploits have been reported in the wild, but the medium CVSS score of 5.5 reflects the significant confidentiality impact balanced against the limited attack vector and privileges required.

For European organizations, this vulnerability poses a risk of sensitive information leakage from Apple devices, particularly those running tvOS in media, entertainment, or corporate environments where Apple TV devices may be used for presentations or digital signage. Confidential data such as credentials, session tokens, or proprietary information could be exposed if an attacker gains local access. While the vulnerability does not affect system integrity or availability, the confidentiality breach could lead to further attacks or data privacy violations under GDPR. Organizations relying on Apple ecosystems for critical operations or handling sensitive data must consider this vulnerability a risk to their information security posture. The risk is higher in environments where physical or local access controls are weak or where devices are shared among multiple users.

To mitigate CVE-2024-54500, European organizations should promptly deploy the security updates released by Apple for all affected platforms, including tvOS 18.2 and the corresponding versions of iPadOS, watchOS, visionOS, macOS, and iOS. Beyond patching, organizations should enforce strict local access controls to Apple devices, limiting physical and network access to trusted personnel only. Implement device management solutions to monitor and restrict installation of untrusted applications or media files that could exploit this vulnerability. Regularly audit device configurations and usage policies to prevent unauthorized local access. Additionally, educate users about the risks of processing untrusted media files and establish incident response procedures to quickly address any suspected memory disclosure incidents. For environments with high security requirements, consider isolating Apple TV devices from sensitive networks or data stores to reduce exposure.
