AnalysisAIv1 – Mar 12, 2026

Out-of-bounds read in Open Babel's CIF file handler (versions up to 3.1.1) allows remote denial of service when processing malicious files. Public exploit code exists for this vulnerability, and no patch is currently available. Attackers can trigger a crash by sending specially crafted input to the affected transform3d function without requiring authentication or user interaction beyond opening a file.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
