Detail

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS Ubuntu 8.04 LTS Ubuntu 8.10 Ubuntu 9.04 Ubuntu 9.10

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 6.06 LTS:
sudo 1.6.8p12-1ubuntu6.2
sudo-ldap 1.6.8p12-1ubuntu6.2

Ubuntu 8.04 LTS:
sudo 1.6.9p10-1ubuntu3.7
sudo-ldap 1.6.9p10-1ubuntu3.7

Ubuntu 8.10:
sudo 1.6.9p17-1ubuntu2.3
sudo-ldap 1.6.9p17-1ubuntu2.3

Ubuntu 9.04:
sudo 1.6.9p17-1ubuntu3.2
sudo-ldap 1.6.9p17-1ubuntu3.2

Ubuntu 9.10:
sudo 1.7.0-1ubuntu2.2
sudo-ldap 1.7.0-1ubuntu2.2

In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Valerio Costamagna discovered that sudo did not properly validate the path for the 'sudoedit' pseudo-command when the PATH contained only a dot ('.'). If secure_path and ignore_dot were disabled, a local attacker could exploit this to execute arbitrary code as root if sudo was configured to allow the attacker to use sudoedit. By default, secure_path is used and the sudoedit pseudo-command is not used in Ubuntu. This is a different but related issue to CVE-2010-0426.

Id Description
63878 sudo sudoedit Command Matching Failure Privilege Escalation

sudo contains a flaw that may allow an attacker to gain access to unauthorized privileges. A user with privilege to execute the sudoedit pseudo-command can place a file with the same name in the current folder and get it executed by sudo, allowing a local attacker to gain execution of arbitrary code as a privileged user, normally root.
