CVE-2025-64894 is an integer overflow or wraparound vulnerability classified under CWE-190, found in Adobe's Digital Negative (DNG) Software Development Kit (SDK) versions 1.7.0 and earlier. The vulnerability arises when the SDK improperly handles integer values during processing of DNG files, potentially causing an overflow or wraparound condition. This can lead to memory corruption or logic errors that cause the application using the SDK to crash or become unresponsive, resulting in a denial-of-service (DoS) condition. Exploitation requires a victim to open a maliciously crafted DNG file, meaning user interaction is necessary. The vulnerability does not allow for code execution or data leakage, but it impacts application availability. The CVSS v3.1 base score is 5.5, reflecting medium severity with the vector AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, indicating local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, no confidentiality or integrity impact, and high impact on availability. No patches or exploits are currently publicly available, but organizations using the DNG SDK in their imaging or media processing pipelines should be aware of the risk. The vulnerability could be triggered by attackers distributing malicious DNG files via email, downloads, or other file-sharing methods. Given the SDK's use in creative and photographic applications, the threat primarily targets software that processes raw image files.

For European organizations, the primary impact is disruption of services or applications that rely on Adobe DNG SDK for processing digital images, particularly in media, photography, and creative industries. A successful exploit could cause denial-of-service conditions, leading to downtime, loss of productivity, and potential reputational damage if critical imaging workflows are interrupted. While no confidentiality or integrity compromise is expected, availability loss can affect business continuity, especially in environments where image processing is integral to operations such as publishing houses, advertising agencies, and digital content creators. The requirement for user interaction limits large-scale automated exploitation but targeted attacks via phishing or malicious file distribution remain plausible. Organizations handling large volumes of DNG files or integrating the SDK into custom software should be particularly vigilant. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available.

1. Monitor Adobe advisories for patches or updates addressing CVE-2025-64894 and apply them promptly once released. 2. Until patches are available, implement strict file validation and scanning for DNG files before processing, using antivirus or specialized file inspection tools to detect malformed or suspicious files. 3. Employ sandboxing or containerization techniques to isolate applications using the DNG SDK, limiting the impact of potential crashes or hangs. 4. Educate users about the risks of opening unsolicited or unexpected DNG files, especially from untrusted sources, to reduce the likelihood of successful exploitation. 5. Review and restrict permissions of applications processing DNG files to minimize potential disruption. 6. Implement robust logging and monitoring to detect abnormal application behavior indicative of exploitation attempts. 7. Consider alternative image processing libraries if timely patches are unavailable and risk is high. 8. Coordinate with incident response teams to prepare for potential denial-of-service incidents related to this vulnerability.
