Package        : perl
Vulnerability  : insecure temporary files / directories
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2004-0452 CAN-2004-0976

Several vulnerabilities have been discovered in Perl, the popular
scripting language.  The Common Vulnerabilities and Exposures project
identifies the following problems:


    Jeroen van Wolffelaar discovered that the rmtree() function in the
    File::Path module removes directory trees in an insecure manner
    which could lead to the removal of arbitrary files and directories
    through a symlink attack.


    Trustix developers discovered several insecure uses of temporary
    files in many modules which allow a local attacker to overwrite
    files via a symlink attack.

For the stable distribution (woody) these problems have been fixed in
version 5.6.1-8.8.

For the unstable distribution (sid) these problems have been fixed in
version 5.8.4-5.

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.
