Enable ExecShield
An XCCDF Group
Description
ExecShield describes kernel features that provide
protection against exploitation of memory corruption errors such as buffer
overflows. These features include random placement of the stack and other
memory regions, prevention of execution in memory that should only hold data,
and special handling of text buffers. These protections are enabled by default
on 32-bit systems and controlled through sysctl variables
kernel.exec-shield and kernel.randomize_va_space. On the latest
64-bit systems, kernel.exec-shield cannot be enabled or disabled with
sysctl.
