Lifecycle Timeline
4DescriptionCVE.org
Bridge versions 16.0.2, 15.1.4 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
AnalysisAI
Heap-based buffer overflow in Adobe Bridge 16.0.2, 15.1.4, and earlier allows arbitrary code execution with user privileges when processing malicious files. CVSS 7.8 (High) reflects the local attack vector requiring victim interaction to open a crafted file. No public exploit identified at time of analysis, with SSVC framework rating this as non-automatable but capable of total technical impact. Exploitation requires social engineering to deliver the malicious file to the target user.
Technical ContextAI
This vulnerability stems from improper bounds checking during heap memory allocation when Adobe Bridge parses specially crafted files. CWE-122 (Heap-based Buffer Overflow) indicates the application writes data beyond allocated heap memory boundaries, allowing an attacker to overwrite adjacent memory structures. Adobe Bridge is a digital asset management application that processes various media file formats, and this flaw likely exists in one of the file parsing libraries or codecs. The heap corruption can be leveraged to redirect program execution flow by overwriting function pointers or virtual tables stored in heap memory, ultimately achieving arbitrary code execution within the security context of the Bridge process.
RemediationAI
Adobe has released patches addressing this vulnerability detailed in security bulletin APSB26-39 at https://helpx.adobe.com/security/products/bridge/apsb26-39.html. Users should immediately upgrade to the patched versions specified in the advisory for their respective product branches. Until patches can be applied, organizations should implement defense-in-depth controls including restricting Bridge usage to trusted file sources only, enabling application sandboxing or virtualization where available, training users to recognize social engineering attempts involving unsolicited file attachments, and monitoring Bridge process behavior for anomalous memory access patterns using endpoint detection and response tools.
