end_pattern (called from internal_fnmatch) in the GNU C Library (aka glibc
or libc6) before 2.22 might allow context-dependent attackers to cause a
denial of service (application crash), as demonstrated by use of the
fnmatch library function with the **(!() pattern. NOTE: this is not the
same as CVE-2015-8984; also, some Linux distributions have fixed
CVE-2015-8984 but have not fixed this additional fnmatch issue.
