1DescriptionCVE.org
DNG SDK versions 1.7.1 2536 and earlier are affected by a NULL Pointer Dereference vulnerability that could result in an application denial-of-service. An attacker could exploit this vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
AnalysisAI
Null Pointer Dereference in Adobe DNG SDK versions 1.7.1 build 2536 and earlier allows an attacker to crash any application embedding the SDK by supplying a specially crafted DNG file. The flaw is strictly a denial-of-service with no confidentiality or integrity impact, and requires a victim to open the malicious file, constraining realistic exposure to imaging pipelines or end-user applications that ingest untrusted DNG content. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a victim actively open a specially crafted DNG file using an application that embeds Adobe DNG SDK version 1.7.1 build 2536 or earlier (CVSS UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 5.5 (Medium) accurately reflects the constrained threat model: AV:L requires the malicious file to be opened on the local system, UI:R mandates victim interaction, and the impact is bounded to A:H with no confidentiality or integrity exposure (C:N/I:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malformed DNG raw image file designed to trigger the null pointer dereference in the SDK parser, then delivers it to a victim via email attachment, shared network folder, or a download link on a compromised website. When the victim opens the file in an application - such as an image editor or DAM client - built on Adobe DNG SDK 1.7.1 build 2536 or earlier, the parser hits the invalid code path and the host application crashes. … |
| Remediation | The primary fix is to update the Adobe DNG SDK to the version specified in Adobe advisory APSB26-67 at https://helpx.adobe.com/security/products/dng-sdk/apsb26-67.html; the exact patched build number should be confirmed directly from that advisory, as it was not present in the source intelligence. … Detailed patch versions, workarounds, and compensating controls in full report. |
