Technical ContextAI · show details

This vulnerability is classified under CWE-824.

Summary A memory-safety vulnerability in Open Babel's PQS parser caused an uninitialized pointer dereference when reading a crafted input file.

Details The flaw was in the `pFormat` handling of the PQS reader. A malformed input caused the parser to dereference a format 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 PQS 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.

Patched version 3.2.0 (released 2026-05-26).

Patch Fix commit: https://github.com/openbabel/openbabel/commit/2a7d2cda A minimized reproducer for this CVE is checked in under `test/files/fuzz_regress/` and is exercised on every CI build under ASAN+UBSAN by the `fuzzregresstest` harness.

Attack Technique

Memory Corruption HIGH

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
