Description
It was found that targets using gcc's libssp library for Stack Smashing Protection (among others: Cygwin, MinGW, newlib, RTEMS; but not Glibc, Bionic, NetBSD which provide SSP in libc), are missing the Object Size Checking feature, even when explicitly requested with _FORTIFY_SOURCE. Vulnerable binaries compiled against such targets do not benefit of such protection, increasing the chances of success of a buffer overflow attack.
