CVE-2015-3027 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.30% chance of exploitation in the next 30 days.
