CVE-2015-1593: Integer Overflow
First published: Fri Feb 13 2015(Updated: )
It was reported [1] that stack address is not properly randomized on some 64 bit architectures due to an integer overflow. The stack entropy of the processes is reduced by four. The possible locations are significantly reduced from around one billion to two hundred millions. The problem seems to affect only to the x86_64 architecture.
