Paul Szabo discovered another vulnerability in the File::Path::rmtree function of perl, the popular scripting language. When a process is deleting a directory tree, a different user could exploit a race condition to create setuid binaries in this directory tree, provided that he already had write permissions in any subdirectory of that tree.
