Submit #654062: Open Babel 3.1.1 / master commit 889c350 Heap-based Buffer Overflowinfo

TitleOpen Babel 3.1.1 / master commit 889c350 Heap-based Buffer Overflow
DescriptionOpen Babel 3.1.1 (master commit 889c350) contains a heap-buffer-overflow vulnerability in the ChemKin format parser (ChemKinFormat::CheckSpecies). When parsing specially crafted ChemKin input, the function uses a corrupted or malformed string as a key for a std::map::find lookup. This can cause out-of-bounds memory access in the underlying red-black tree structure, leading to program crashes and denial of service.
