GLSA-200409-15 : Webmin, Usermin: Multiple vulnerabilities in Usermin

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200409-15
(Webmin, Usermin: Multiple vulnerabilities in Usermin)

There is an input validation bug in the webmail feature of Usermin.
Additionally, the Webmin and Usermin installation scripts write to
/tmp/.webmin without properly checking if it exists first.

Impact :

The first vulnerability allows a remote attacker to inject arbitrary
shell code in a specially crafted e-mail. This could lead to remote
code execution with the privileges of the user running Webmin or
Usermin.
The second could allow local users who know Webmin or Usermin is going
to be installed to have arbitrary files be overwritten by creating a
symlink by the name /tmp/.webmin that points to some target file, e.g.
/etc/passwd.

Workaround :

There is no known workaround at this time.

# emerge sync
# emerge -pv '>=app-admin/usermin-1.090'
