CVE-2017-1000366: Buffer Overflow
A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the heap/stack gap, cause controlled memory corruption on process stack or heap, and thus increase their privileges on the system.
This is a tracking bug for the glibc part of the mitigation.
Other sources
glibc contains a vulnerability that allows specially crafted LDLIBRARYPATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.
