CVE-2015-3027

Estado: ModificadaMedia (5)—

Clang in LLVM, as used in Apple Xcode before 6.3, performs incorrect register allocation in a way that triggers stack storage for stack cookie pointers, which might allow context-dependent attackers to bypass a stack-guard protection mechanism via crafted input to an affected C program.
