Red Hat upgrades security
Red Hat released an update to its enterprise product with security upgrades, support for IBM Power5 servers, new driver support and bug fixes.
The security upgrades in Enterprise Linux 3 Update 3 include Exec-shield and Position Independent Executable (PIE) features to protect against stack, buffer or function pointer overflows and other exploits that involve overwriting data structures in memory. No-execute (NX) support will now be available for Intel x86, Intel EM64T and Advanced Micro Devices AMD64 processors.
