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...

Linux ASLR mmap weakness: Reducing entropy by half

A bug in Linux ASLR implementation has been found. The issue is that the mmap base address for processes is not properly randomized on some architectures due to an improper bit-mask manipulation. Affected systems have reduced the mmap area entropy of the processes by half. The number of possible...
