Paul Szabo rediscovered a vulnerability in the File::Path::rmtree
function of Perl. It was possible to exploit a race condition to create
setuid binaries in a directory tree or remove arbitrary files when a
process is deleting this tree. This issue was originally known as
CVE-2005-0448 and CVE-2004-0452, which were addressed by DSA-696-1 and
DSA-620-1. Unfortunately, they were reintroduced later.
