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.
For the stable distribution (etch), these problems have been fixed in
version 5.8.8-7etch5.
For the unstable distribution (sid), these problems have been fixed in
version 5.10.0-18 and will migrate to the testing distribution (lenny)
shortly.
We recommend that you upgrade your perl packages.
