Newer versions of gcc and binutils support generation of position independent executables (PIE) using the option -fpie for gcc and -pie for ld. the result is a ELF shared object that can be executed instead of a ELF executable. The difference is that PIE executables can be loaded at any address and support address randomization in order to make vulnerability exploits harder.
In Debian you can create and execute such PIE executables but their address spaces are not randomized (I've checked with printf() and cat /proc/<pid>/maps). I assume you need kernel support for this and the standard Debian kernel doesn't have it. So is there a way to get PIE executables with random addresses on Debian? urs -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
