CVE-2025-64784 identifies a heap-based buffer overflow vulnerability (CWE-122) in Adobe's Digital Negative (DNG) Software Development Kit (SDK) versions 1.7.0 and earlier. This vulnerability arises when the SDK improperly handles memory allocation or bounds checking during the processing of DNG files, allowing an attacker to overflow a heap buffer. The overflow can lead to the exposure of sensitive memory contents or cause the application to crash, resulting in denial of service. Exploitation requires that a victim opens a specially crafted malicious DNG file, which triggers the vulnerability during file parsing. The vulnerability affects confidentiality by potentially leaking sensitive memory data and availability by crashing the application, but it does not impact data integrity. The attack vector is local (AV:L), requiring low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R). The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component. The CVSS v3.1 base score is 7.1, categorizing it as high severity. Currently, no public exploits or patches are available, but the vulnerability has been officially published and reserved by Adobe. This SDK is commonly used in applications that handle digital photography and imaging workflows, making it relevant for organizations processing DNG files.

For European organizations, the vulnerability poses a risk primarily to confidentiality and availability. Sensitive memory exposure could lead to leakage of private or proprietary information processed by applications using the Adobe DNG SDK. Denial of service could disrupt imaging workflows, affecting productivity and service availability. Organizations in creative industries, digital media, photography, and publishing that rely on software integrating this SDK are particularly vulnerable. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where users frequently open external or untrusted image files. The absence of known exploits reduces immediate risk but underscores the importance of proactive mitigation. Disruptions could impact business continuity and data privacy compliance obligations under GDPR if sensitive data is exposed.

Until Adobe releases a patch, organizations should implement strict controls on file sources, restricting the opening of DNG files from untrusted or unknown origins. Employ sandboxing or containerization for applications processing DNG files to limit the impact of potential exploitation. Enable application-level protections such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) to mitigate exploitation success. Monitor user activity and file access logs for unusual behavior related to DNG file handling. Educate users on the risks of opening unsolicited or suspicious image files. Once Adobe releases a security update, prioritize patching affected systems promptly. Additionally, consider using alternative software solutions that do not rely on vulnerable versions of the DNG SDK where feasible.
