Summary
A weakness has been identified in niklasso minisat up to 2.2.0. This issue affects the function Solver::value in the library core/SolverTypes.h of the component DIMACS File Parser. This manipulation of the argument variable index with the input 2147483648 causes out-of-bounds read. The attack needs to be launched locally.
