Two Gentoo Linux Security Advisories:

1. GLSA 200504-20 - openMosixview: Insecure temporary file creation

2. GLSA 200504-21 - RealPlayer, Helix Player: Buffer overflow vulnerability

Detail
======

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

2. Piotr Bania has discovered a buffer overflow vulnerability in
RealPlayer and Helix Player when processing malicious RAM files.

Bugs: #86686
ID: 200504-20

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"

Title: RealPlayer, Helix Player: Buffer overflow vulnerability
Date: April 22, 2005
Bugs: #89862
ID: 200504-21

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Synopsis
========

RealPlayer and Helix Player are vulnerable to a buffer overflow that
could lead to remote execution of arbitrary code.

Background
==========

RealPlayer is a multimedia player capable of handling multiple
multimedia file formats. Helix Player is the Open Source version of
RealPlayer.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/realplayer < 10.0.4 >= 10.0.4
2 media-video/helixplayer < 1.0.4 >= 1.0.4
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

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

Piotr Bania has discovered a buffer overflow vulnerability in
RealPlayer and Helix Player when processing malicious RAM files.

Impact
======

By enticing a user to play a specially crafted RAM file an attacker
could execute arbitrary code with the permissions of the user running
the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All RealPlayer users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/realplayer-10.0.4"

All Helix Player users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/helixplayer-1.0.4"
