Synopsis
========

openMosixview and the openMosixcollector daemon are vulnerable to
symlink attacks, potentially allowing a local user to overwrite
arbitrary files.

Background
==========

The openMosixview package contains several tools used to manage
openMosix clusters, including openMosixview (the main monitoring and
administration application) and openMosixcollector (a daemon collecting
cluster and node information).

Affected packages
=================

    -------------------------------------------------------------------
     Package                    /  Vulnerable  /            Unaffected
    -------------------------------------------------------------------
  1  sys-cluster/openmosixview      < 1.5-r1                 >= 1.5-r1

Description
===========

Gangstuck and Psirac from Rexotec discovered that openMosixview
insecurely creates several temporary files with predictable filenames.

Impact
======

A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
openMosixView or the openMosixcollector daemon runs, this would result
in the file being overwritten with the rights of the user running the
utility, which could be the root user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All openMosixview users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=sys-cluster/openmosixview-1.5-r1"

Availability
============

This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:

Concerns?
=========

Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users machines is of utmost
importance to us. Any security concerns should be addressed to
security@gentoo.org or alternatively, you may file a bug at

- 漏洞讨论

openMosixview is reported prone to multiple local insecure temporary file creation vulnerabilities. These issues are due to design errors that cause the application to fail to verify the existence of files before writing to them.

An attacker may leverage these issues to overwrite and delete arbitrary files with the privileges of an unsuspecting user that activates the vulnerable application.

All versions of openMosixView are reported vulnerable.

- 漏洞利用

An exploit is not required.

Proof of concept is available:

- 解决方案

Gentoo has released an advisory (GLSA 200504-20) and an updated eBuild to address this issue. Gentoo users may apply the updates by issuing the following sequence of commands as a superuser:
emerge --sync
emerge --ask --oneshot --verbose ">=sys-cluster/openmosixview-1.5-r1"
