Severity: Normal
Title: Webmin: Multiple vulnerabilities
Date: June 16, 2004
Bugs: #53375
ID: 200406-12

---

Synopsis

Webmin contains two security vulnerabilities which could lead to
a Denial of Service attack and information disclosure.

Background

Webmin is a web-based administration tool for Unix. It supports
a wide range of applications including Apache, DNS, file sharing
and others.

Affected packages

Description

Webmin contains two security vulnerabilities. One allows any
user to view the configuration of any module and the other could
allow an attacker to lock out a valid user by sending an invalid
username and password.

Impact

An authenticated user could use these vulnerabilities to view
the configuration of any module thus potentially obtaining
important knowledge about configuration settings. Furthermore an
attacker could lock out legitimate users by sending invalid login
information.

Workaround

There is no known workaround at this time.

Resolution

All Webmin users should upgrade to the latest stable
version:

    # emerge sync
    # emerge -pv ">=app-admin/app-admin/webmin-1.150"
    # emerge ">=app-admin/app-admin/webmin-1.150"

Synopsis

An input validation vulnerability has been discovered in
Horde-IMP.

Background

Horde-IMP is the Internet Messaging Program. It is written in
PHP and provides webmail access to IMAP and POP3 accounts.

Affected packages

Description

malicious HTML or script code.

Impact

attacker can execute arbitrary scripts running in the context of
the victim’s browser. This could lead to a compromise of the user’s
webmail account, cookie theft, etc.

Workaround

There is no known workaround at this time.
