Detail
======
Security advisory summaries:
1. The SELinux patches for PAM introduce a vulnerability allowing a
password to be checked with the unix_chkpwd utility without delay or
logging. This vulnerability doesn't affect users who do not run
SELinux.
2. Due to improper input validation, TikiWiki can be exploited to perform
cross-site scripting attacks.
3. Mantis contains several vulnerabilities, including:
* a remote file inclusion vulnerability
* an SQL injection vulnerability
* multiple cross site scripting vulnerabilities
* multiple information disclosure vulnerabilities

Synopsis
========
A vulnerability in the SELinux version of PAM allows a local attacker
to brute-force system passwords.
Background
==========
PAM (Pluggable Authentication Modules) is an architecture allowing the
separation of the development of privilege granting software from the
development of secure and appropriate authentication schemes. SELinux
is an operating system based on Linux which includes Mandatory Access
Control.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-libs/pam < 0.78-r3 >= 0.78-r3
Description
===========
The SELinux patches for PAM introduce a vulnerability allowing a
password to be checked with the unix_chkpwd utility without delay or
logging. This vulnerability doesn't affect users who do not run
SELinux.
Impact
======
A local attacker could exploit this vulnerability to brute-force
passwords and escalate privileges on an SELinux system.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All SELinux PAM users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/pam-0.78-r3"

Title: TikiWiki: XSS vulnerability
Date: October 28, 2005
Bugs: #109858
ID: 200510-23
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
TikiWiki is vulnerable to cross-site scripting attacks.
Background
==========
TikiWiki is a web-based groupware and content management system (CMS),
using PHP, ADOdb and Smarty.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/tikiwiki < 1.9.1.1 >= 1.9.1.1
Description
===========
Due to improper input validation, TikiWiki can be exploited to perform
cross-site scripting attacks.
Impact
======
A remote attacker could exploit this 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 TikiWiki users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/tikiwiki-1.9.1.1"
Note: Users with the vhosts USE flag set should manually use
webapp-config to finalize the update.

Title: Mantis: Multiple vulnerabilities
Date: October 28, 2005
Bugs: #110326
ID: 200510-24
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Mantis is affected by multiple vulnerabilities ranging from information
disclosure to arbitrary script execution.
Background
==========
Mantis is a web-based bugtracking system written in PHP.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/mantisbt < 0.19.3 >= 0.19.3
Description
===========
Mantis contains several vulnerabilities, including:
* a remote file inclusion vulnerability
* an SQL injection vulnerability
* multiple cross site scripting vulnerabilities
* multiple information disclosure vulnerabilities
Impact
======
An attacker could exploit the remote file inclusion vulnerability to
execute arbitrary script code, and the SQL injection vulnerability to
access or modify sensitive 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. An attacker could exploit other vulnerabilities to
disclose information.
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-0.19.3"
