Posted on: 04/17/2004 04:14 AM

An updated perl package has been released for Debian GNU/Linux

Debian Security Advisory DSA 431-2 security@debian.org
http://www.debian.org/security/ Matt Zimmerman
April 16th, 2004 http://www.debian.org/security/faq
---------------------------------------------------------------------------

Package : perl
Vulnerability : information leak
Problem-Type : local
Debian-specific: no
CVE Ids : CAN-2003-0618

Paul Szabo discovered a number of similar bugs in suidperl, a helper program to run perl scripts with setuid privileges. By exploiting these bugs, an attacker could abuse suidperl to discover information about files (such as testing for their existence and some of their permissions) that should not be accessible to unprivileged users.

DSA 431-1 incorporated a partial fix for this problem. This advisory includes a more complete fix which corrects some additional cases.

For the current stable distribution (woody) this problem has been fixed in version 5.6.1-8.7.

For the unstable distribution, this problem has been fixed in version 5.8.3-3.

We recommend that you update your perl package if you have the "perl-suid" package installed.

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.
