The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not "properly restrict the use of" the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers, a different vulnerability than CVE-2012-3404 and CVE-2012-3405.

CVE-2012-3406 glibc: printf() unbound alloca() usage in case of positional parameters + many format specs
It was discovered that the formatted printing functionality in glibc did not properly restrict the use of alloca(). A remote attacker could provide a specially crafted sequence of format specifiers, leading to a crash or, potentially, FORTIFY_SOURCE format string protection mechanism bypass, when processed.
