CVE-2011-1659

Integer overflow in posix/fnmatch.c in the GNU C Library (aka glibc or libc6) 2.13 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long UTF8 string that is used in an fnmatch call with a crafted pattern argument, a different vulnerability than CVE-2011-1071.
