Open Babel has heap buffer overflow in SMILES OBSmilesParser::ParseSmiles
ghsa·2026-06-30
CVE-2025-10996 [HIGH] CWE-119 Open Babel has heap buffer overflow in SMILES OBSmilesParser::ParseSmiles
Open Babel has heap buffer overflow in SMILES OBSmilesParser::ParseSmiles
### Summary
A memory-safety vulnerability in Open Babel's SMILES parser caused a
heap buffer overflow when reading a crafted input string.
### Details
The flaw was in `OBSmilesParser::ParseSmiles`. A malformed SMILES
input caused the parser to write past the end of a heap-allocated
buffer.
### Impact
Open Babel is a C++ library and CLI used to read and write chemistry
file formats; it is shipped by Linux distributions and embedded in
services that may parse untrusted input. Triggering this vulnerability
requires the victim to parse a malicious SMILES string with the
`obabel` tool, the `OBConversion` API, or any of the language
bindings (Python, Ruby, Java, R, Perl, C#, PHP). SMILES strings are
commonly passed o
