The vfprintf function in stdio-common/vfprintf.c in libc in GNU C Library
(aka glibc) 2.12 and other versions does not properly calculate a buffer
length, which allows context-dependent attackers to bypass the
FORTIFY_SOURCE format-string protection mechanism and cause a denial of
service (stack corruption and crash) via a format string that uses
positional parameters and many format specifiers.
