Multiple out-of-bounds write vulnerabilities exist in the translationVectors parsing functionality in multiple supported formats of Open Bab
Multiple out-of-bounds write vulnerabilities exist in the translationVectors parsing functionality in multiple supported formats of Open Babel 3.1.1 and master commit 530dbfa3. A specially-crafted malformed file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.This vulnerability affects the MOPAC file format, inside the Unit Cell Translation section

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
