Package        : sudo
Vulnerability  : missing input sanitization
Problem type   : local
Debian-specific: no
CVE Id         : CVE-2010-1646
Debian Bug     : 585394


Anders Kaseorg and Evan Broder discovered a vulnerability in sudo, a
program designed to allow a sysadmin to give limited root privileges to
users, that allows a user with sudo permissions on certain programs to
use those programs with an untrusted value of PATH.
This could possibly lead to certain intended restrictions being bypassed,
such as the secure_path setting.


For the stable distribution (lenny), this problem has been fixed in
version 1.6.9p17-3

For the unstable distribution (sid), this problem has been fixed in
version 1.7.2p7-1, and will migrate to the testing distribution (squeeze)
shortly.


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.
