Submit #654064: Open Babel 3.1.1 / master commit 889c350 NULL Pointer Dereferenceinfo

TitleOpen Babel 3.1.1 / master commit 889c350 NULL Pointer Dereference
DescriptionOpen Babel 3.1.1 (master commit 889c350) contains a null pointer dereference vulnerability in the Cacao format parser. Specifically, the function CacaoFormat::SetHilderbrandt assumes that all OBAtom* pointers in its internal coordinate list are valid. When a crafted input causes a null or corrupted atom pointer to be inserted, the code calls OBAtom::GetIdx() on this invalid pointer, leading to a crash at address 0x30.
