CVE-2018-11236: glibc: Integer overflow in stdlib/canonicalize.c on 32-bit architectures leading to stack-based buffer overflow

Severity: Critical

CVSS Score: 9.8

stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution.
