GNU C Library (glibc) contains an integer overflow condition in the 'fnmatch' function [posix/fnmatch.c] that is triggered as user-supplied UTF-8 strings are not properly validated. With a specially crafted string, a remote attacker can cause an out-of-bounds read access violation, crashing an application linked against the library.
