*const c_void / ExternalPointer unsoundness leading to use-after-free

Summary Use of inherently unsafe const cvoid and ExternalPointer leads to use-after-free access of the underlying structure, resulting in arbitrary code execution. Details const cvoid and ExternalPointer defined via external! macros types are used to represent v8::External wrapping arbitrary void...

CVE-2017-1000253

A flaw was found in the way the Linux kernel loaded ELF executables. Provided that an application was built as Position Independent Executable PIE, the loader could allow part of that application's data segment to map over the memory area reserved for its stack, potentially resulting in memory...
