Debian DSA-596-2 : sudo - missing input sanitising

high Nessus Plugin ID 15825

Synopsis

The remote Debian host is missing a security-related update.

Description

Liam Helmer noticed that sudo, a program that provides limited super user privileges to specific users, does not clean the environment sufficiently. Bash functions and the CDPATH variable are still passed through to the program running as privileged user, leaving possibilities to overload system routines. These vulnerabilities can only be exploited by users who have been granted limited super user privileges.

Solution

Upgrade the sudo package.

For the stable distribution (woody) these problems have been fixed in version 1.6.6-1.3.
