Openbabel: Duplicate Advisory: Open Babel has out-of-bounds write in MOPAC translationVectors[] (UNIT CELL TRANSLATION)
## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-55f6-pf8r-c2f4. This link is maintained to preserve external references. ## Original Description 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
AI Analysis
Technical Summary
Open Babel 3.1.1 and earlier versions have multiple out-of-bounds write vulnerabilities in the translationVectors parsing code related to the MOPAC file format's Unit Cell Translation section. An attacker can exploit these flaws by providing a maliciously crafted file, which may result in arbitrary code execution. This vulnerability is tracked as GHSA-hrvg-gx3j-wh53 but is a duplicate of GHSA-55f6-pf8r-c2f4. The CVSS 3.1 base score is critical, reflecting high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to arbitrary code execution, compromising system confidentiality, integrity, and availability. The vulnerability arises from out-of-bounds writes during parsing of the MOPAC file format, which can be triggered remotely by supplying a crafted file.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in this advisory. Users should monitor the official Open Babel project communications for updates and apply patches once available. Until then, avoid processing untrusted MOPAC files with affected versions.
