Mandrake Linux Security Advisory : sudo (MDKSA-2005:234)

This script is Copyright (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandrake Linux host is missing a security update.

Description :

Charles Morris discovered a vulnerability in sudo versions prior to
1.6.8p12 where, when the perl taint flag is off, sudo does not clear
the PERLLIB, PERL5LIB, and PERL5OPT environment variables, which could
allow limited local users to cause a perl script to include and
execute arbitrary library files that have the same name as library
files that included by the script.

In addition, other environment variables have been included in the
patch that remove similar environment variables that could be used in
python and ruby, scripts, among others.

The updated packages have been patched to correct this problem.
