| Title | Open Babel 3.1.1 / master commit 889c350 NULL Pointer Dereference |
|---|
| Description | Open Babel 3.1.1 (master commit 889c350) contains a null pointer dereference vulnerability in the ChemKin format parser (ChemKinFormat::ReadReactionQualifierLines). When parsing specially crafted ChemKin input, the function calls std::string::c_str() on a null or invalid string object. This leads to a segmentation fault and denial of service when dereferencing the null pointer. |
