Hello Mitre,

Any update about this issue ?

Hi,

A bug in Linux ASLR implementation for versions prior to 3.19 has been found.
The issue is that the mmap area for processes is not properly randomized on some
architectures.

Affected systems have reduced the mmap base area entropy of the processes by half.


Details at:

Could you please assign a CVE-ID for this?
