Debian: New perl packages fix privilege escalation Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Debian 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.

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.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
