Whiteboard:
Fixed In Version: binutils-2.20.51.0.2-5.44.el6 Doc Type: Bug Fix
Doc Text:
RELRO protection now properly applied when requested Previously, binary files started by the system loader would, in some cases, lack the Relocation Read-Only (RELRO) protection even though this had been explicitly requested when the application was built. This was due to a miscommunication between the static linker and the system loader. The underlying source code of the linker has been adjusted to ensure that it makes it possible for the loader to apply the RELRO protection, thus restoring the security feature for applications. Applications and all dependent object files, archives, and libraries built with a previous version of _binutils_ should be rebuilt to correct this defect.
