DSA 735-1: New sudo packages fix pathname validation race

New sudo packages are available for Debian GNU/Linux

Debian Security Advisory 735-1 security@debian.org

-------------------------------------------------------------------------

Package : sudo
Vulnerability : pathname validation race
Problem type : local
Debian-specific: no
CVE Id(s) : CAN-2005-1993
Debian Bug : 315115

A local user who has been granted permission to run commands via sudo could run arbitrary commands as a privileged user due to a flaw in sudo's pathname validation. This bug only affects configurations which have restricted user configurations prior to an ALL directive in the configuration file. A workaround is to move any ALL directives to the beginning of the sudoers file; see the advisory at http://www.sudo.ws/sudo/alerts/path_race.html for more information.

For the old stable Debian distribution (woody), this problem has been fixed in version 1.6.6-1.3woody1. For the current stable distribution (sarge), this problem has been fixed in version 1.6.8p7-1.1sarge1. Note that packages are not yet ready for certain architectures; these will be released as they become available.

We recommend that you upgrade your sudo package.

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.
