AMD Bulldozer Linux ASLR weakness: Reducing entropy by 87.5%

A security issue in Linux ASLR implementation which affects some AMD processors has been found. The issue affects to all Linux process even if they are not using shared libraries statically compiled. The problem appears because some mmapped objects VDSO, libraries, etc. are poorly randomized in a...
