Gentoo - Two Security Advisories:
1. Mantis: XSS and SQL injection vulnerabilities [GLSA 200509-16]
2. Webmin, Usermin: Remote code execution through PAM authentication [GLSA 200509-17]
Detail
======
Security advisory summaries:
1. Mantis fails to properly sanitize untrusted input before using it. This
leads to an SQL injection and several cross-site scripting
vulnerabilities.
2. If Webmin or Usermin is configured to use full PAM conversations, it is
vulnerable to the remote execution of arbitrary code with root
privileges.

Synopsis
========
Mantis is affected by an SQL injection and several cross-site scripting
(XSS) vulnerabilities.
Background
==========
Mantis is a web-based bugtracking system written in PHP.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/mantisbt < 0.19.2 >= 0.19.2
Description
===========
Mantis fails to properly sanitize untrusted input before using it. This
leads to an SQL injection and several cross-site scripting
vulnerabilities.
Impact
======
An attacker could possibly use the SQL injection vulnerability to
access or modify information from the Mantis database. Furthermore the
cross-site scripting issues give an attacker the ability to inject and
execute malicious script code or to steal cookie-based authentication
credentials, potentially compromising the victim's browser.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Mantis users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/mantisbt-0.19.2"

Severity: High
Title: Webmin, Usermin: Remote code execution through PAM
authentication
Date: September 24, 2005
Bugs: #106705
ID: 200509-17
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
If Webmin or Usermin is configured to use full PAM conversations, it is
vulnerable to the remote execution of arbitrary code with root
privileges.
Background
==========
Webmin and Usermin are web-based system administration consoles. Webmin
allows an administrator to easily configure servers and other features.
Usermin allows users to configure their own accounts, execute commands,
and read e-mails.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/webmin < 1.230 >= 1.230
2 app-admin/usermin < 1.160 >= 1.160
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Keigo Yamazaki discovered that the miniserv.pl webserver, used in both
Webmin and Usermin, does not properly validate authentication
credentials before sending them to the PAM (Pluggable Authentication
Modules) authentication process. The default configuration shipped with
Gentoo does not enable the "full PAM conversations" option and is
therefore unaffected by this flaw.
Impact
======
A remote attacker could bypass the authentication process and run any
command as the root user on the target server.
Workaround
==========
Do not enable "full PAM conversations" in the Authentication options of
Webmin and Usermin.
Resolution
==========
All Webmin users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/webmin-1.230"
All Usermin users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/usermin-1.160"
