Update to KSR[T] Advisory #002 Our advisory contained one serious piece of mis-information. The latest version of ld.so that we tested (1.9.2) still appeared to be vulnerable to this overflow. We strongly recommend that anyone running linux install the patch distributed with the advisory, or wait for your vendor to release an updated ld.so package and install that as soon as possible. The

This happens on NonStop x86 and ia64. I have been building/packaging Rsync for years ? almost a decade in fact. I think this happened once before this year, in fact. It is equivalent to the more portable malloc/free, which I would prefer to have in this series even if it has to be wrapped in a #if defined (__TANDEM) block. This call is considered not portable and allocates on the stack

Hello, On macOS, Terminal?s ?New Remote Connection?? command runs ssh in a new window like this: login -pfq $USER /usr/bin/ssh $HOST Here, login executes /usr/bin/ssh with argv[0] set to ?-ssh?. If $HOST has a ProxyJump configuration, the resulting ProxyCommand is: -ssh -W '[%h]:%p' $JUMP_HOST Because of the leading hyphen, this fails to execute. If the user?s shell is zsh, the
