CVE-2018-11236 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 7.40% chance of exploitation in the next 30 days.
