CVE-2025-64783 is an integer overflow or wraparound vulnerability (CWE-190) found in Adobe's Digital Negative (DNG) Software Development Kit (SDK) versions 1.7.0 and earlier. The flaw arises when the SDK improperly handles integer values during processing of DNG files, potentially causing an overflow that leads to memory corruption. This memory corruption can be exploited by an attacker to execute arbitrary code within the context of the current user. The attack vector requires the victim to open a maliciously crafted DNG file, which triggers the overflow condition. The vulnerability does not require prior authentication but does require user interaction, specifically opening the malicious file. The CVSS v3.1 base score is 7.8, indicating a high severity due to the combination of local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), required user interaction (UI:R), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits have been reported in the wild, the potential for arbitrary code execution makes this a significant threat, especially in environments where DNG files are processed or handled regularly. The lack of available patches at the time of reporting means organizations must rely on interim mitigations until Adobe releases a fix.

For European organizations, this vulnerability poses a serious risk to systems that utilize Adobe DNG SDK for processing digital images, particularly in industries such as media, photography, advertising, and creative content production. Successful exploitation could lead to unauthorized code execution, allowing attackers to compromise system confidentiality, integrity, and availability. This could result in data theft, system manipulation, or disruption of critical workflows. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to deliver malicious DNG files. The impact is heightened in environments where users have elevated privileges or where the SDK is integrated into automated processing pipelines. Additionally, compromised systems could serve as footholds for lateral movement within networks, increasing the risk of broader organizational compromise.

Organizations should implement the following specific mitigations: 1) Monitor Adobe's security advisories closely and apply patches or updates to the DNG SDK as soon as they become available. 2) Restrict the acceptance and opening of DNG files from untrusted or unknown sources, especially in email and file-sharing platforms. 3) Employ application whitelisting and sandboxing techniques to limit the execution context of applications handling DNG files. 4) Use endpoint detection and response (EDR) tools to monitor for anomalous behaviors indicative of exploitation attempts. 5) Train users to recognize suspicious files and avoid opening unexpected attachments, particularly DNG files. 6) Where possible, isolate systems that process DNG files from critical network segments to reduce potential lateral movement. 7) Conduct regular vulnerability assessments and penetration testing focused on image processing workflows to identify potential exploitation paths.
