InformationAddress space layout randomization (ASLR) is an exploit mitigation technique which randomly arranges the address space of key data areas of a process.
Randomly placing virtual memory regions will make it difficult to write memory page exploits as the memory placement will be consistently shifting.
SolutionSet the following parameter in `/etc/sysctl.conf` or a `/etc/sysctl.d/*` file:
kernel.randomize_va_space = 2
Run the following command to set the active kernel parameter:
# sysctl -w kernel.randomize_va_space=2
