CVE-2017-1000253

About CVE-2017-1000253 Bug:

This issue is related to the Linux kernel loaded Executable and Linkable Format (ELF) executables. If an ELF application was built as Position Independent Executable (PIE), the loader can allow part of that application’s data segment to map over the memory area reserved for its stack.
It  can cause memory corruption and may allow an unprivileged local user to gain privileged access using Set owner User ID (SUID) or privileged flawed PIE binary.
