CVE-2017-15670
The GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-one error leading to a heap-based buffer overflow in the glob function in glob.c, related to the processing of home directories using the ~ operator followed by a long string.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
