What's new in Sudo 1.7.10?
+ * Sudo is now built with the -fstack-protector flag if the the
+ compiler supports it. Also, the -zrelro linker flag is used if
+ supported. The --disable-hardening configure option can be used
+ to build sudo without stack smashing support.
+
* If the user is a member of the "exempt" group in sudoers, they
will no longer be prompted for a password even if the -k flag
is specified with the command. This makes "sudo -k command"
