Easy one. Execute "/lib/ld-linux.so.2 /tmp/code".This long-standing issue is fixed in the Linux 2.6.0 kernel.
How is it an issue? I think it is a feature - it is noexec that is pretty badly broken by design, and nearly impossible to render secure... and what does Linux kernel have to do with addressing it? Disclaimer: I don't have 2.6 sources at hand, maybe this is the case (although I somehow doubt there is a reasonable way to fix it kernel - how, by refusing PROT_EXEC mappings from files on noexec partitions? hope not). -- ------------------------- bash$ :(){ :|:&};: -- Michal Zalewski * [http://lcamtuf.coredump.cx] Did you know that clones never use mirrors? --------------------------- 2004-01-19 19:58 -- http://lcamtuf.coredump.cx/photo/current/ _______________________________________________ Full-Disclosure - We believe in it.
