(Debian Issues Fix) Sudo System Administration Utility May Allow Local Users to Obtain Root Privileges on the Host By Executing Code Via Sendmail
SecurityTracker Alert ID:  1003213
SecurityTracker URL:  http://securitytracker.com/id/1003213
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jan 14 2002
Impact:   Execution of arbitrary code via local system, Root access via local system
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   The SuSE Security Team reported a vulnerability in sudo. A local user may be able to execute code on the host and obtain root privileges.

It is reported that a local user may be able to cause sudo to log failed sudo invocations and execute mail with root privileges while retaining some environment settings. Depending on the mail server that is installed, the local user could execute mail (e.g., sendmail in certain configurations, postfix) with root privileges and execute arbitrary code with root privileges.

Impact:   A local user could obtain root privileges on the host.
Solution:   The vendor has released a fix in Debain version 1.6.2p2-2.1 for the stable release of Debian GNU/Linux and recommends that you upgrade your sudo packages immediately.
