Debian Security Advisory 735-1                       security@...ian.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.


Debian 3.0 (woody)
- ------------------

  woody was released for alpha, arm, hppa, i386, ia64, m68k, mips, mipsel, powerpc, s390 and sparc.
