🔬 Technical Analysis

#

Summary A memory-safety vulnerability in Open Babel's MSI parser caused an

uninitialized pointer dereference when reading a crafted input file.

Details The flaw was in the atom handling of the MSI reader. A malformed

record caused the parser to dereference an atom pointer that had never been initialized.

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 open a malicious MSI file with the obabel tool, the OBConversion API, or any of the language bindings (Python, Ruby, Java, R, Perl, C#, PHP).

Affected versions All releases up to and including 3.1.1.
