90: Josh Bressers has reported a weakness in OpenSSH caused due to the insecure use of the

92: function in

94: when performing copy operations using filenames that are supplied by the user from the command line.
95: This can be exploited to execute shell commands with privileges of the user running

115: Change the implementation of i386 W^X so that the "execute line" can move around.
116: Before it was limited to being either at 512MB (below which all code normally
117: lands) or at the top of the stack. Now the line can float as

121: requests need it to. This is now implemented using only GDT selectors
122: instead of the LDT so that it is more robust as well.
