Title
=====
Four Gentoo Linux Security Advisories:
1. GLSA 200506-13 - webapp-config
2. GLSA 200506-14 - Sun and Blackdown Java
3. GLSA 200506-15 - PeerCast
4. GLSA 200506-16 - cpio
Detail
======
1. Eric Romang discovered webapp-config uses a predictable temporary
filename while processing certain options, resulting in a race
condition.
2. Both Sun's and Blackdown's JDK and JRE may allow untrusted applets to
elevate privileges.
3. James Bercegay of the GulfTech Security Research Team discovered that
PeerCast insecurely implements formatted printing when receiving a
request with a malformed URL.
4. A vulnerability has been found in cpio that can potentially allow a
cpio archive to extract its files to an arbitrary directory of the
creator's choice.

Title: webapp-config: Insecure temporary file handling
Date: June 17, 2005
Bugs: #91785, #88831
ID: 200506-13
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
The webapp-config utility insecurely creates temporary files in a world
writable directory, potentially allowing the execution of arbitrary
commands.
Background
==========
webapp-config is a Gentoo Linux utility to help manage the installation
of web-based applications.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-www/webapp-config < 1.11 >= 1.11
Description
===========
Eric Romang discovered webapp-config uses a predictable temporary
filename while processing certain options, resulting in a race
condition.
Impact
======
Successful exploitation of the race condition would allow an attacker
to disrupt the operation of webapp-config, or execute arbitrary shell
commands with the privileges of the user running webapp-config. A local
attacker could use a symlink attack to create or overwrite files with
the permissions of the user running webapp-config.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All webapp-config users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-www/webapp-config-1.11"

============
This GLSA and any updates to it are available for viewing at

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

Title: Sun and Blackdown Java: Applet privilege escalation
Date: June 19, 2005
Bugs: #96092, #96229
ID: 200506-14
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Sun's and Blackdown's JDK or JRE may allow untrusted applets to elevate
their privileges.
Background
==========
Sun and Blackdown both provide implementations of the Java Development
Kit (JDK) and Java Runtime Environment (JRE).
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/sun-jdk < 1.4.2.08 >= 1.4.2.08
2 dev-java/sun-jre-bin < 1.4.2.08 >= 1.4.2.08
3 dev-java/blackdown-jdk < 1.4.2.02 >= 1.4.2.02
4 dev-java/blackdown-jre < 1.4.2.02 >= 1.4.2.02
-------------------------------------------------------------------
4 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Both Sun's and Blackdown's JDK and JRE may allow untrusted applets to
elevate privileges.
Impact
======
A remote attacker could embed a malicious Java applet in a web page and
entice a victim to view it. This applet can then bypass security
restrictions and execute any command or access any file with the rights
of the user running the web browser.
Workaround
==========
There are no known workarounds at this time.
Resolution
==========
All Sun JDK users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.08"
All Sun JRE users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.08"
All Blackdown JDK users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/blackdown-jdk-1.4.2.02"
All Blackdown JRE users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/blackdown-jre-1.4.2.02"
Note to SPARC users: There is no stable secure Blackdown Java for the
SPARC architecture. Affected users should remove the package until a
SPARC package is released.

Title: PeerCast: Format string vulnerability
Date: June 19, 2005
Bugs: #96199
ID: 200506-15
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
PeerCast suffers from a format string vulnerability that could allow
arbitrary code execution.
Background
==========
PeerCast is a media streaming system based on P2P technology.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-sound/peercast < 0.1212 >= 0.1212
Description
===========
James Bercegay of the GulfTech Security Research Team discovered that
PeerCast insecurely implements formatted printing when receiving a
request with a malformed URL.
Impact
======
A remote attacker could exploit this vulnerability by sending a request
with a specially crafted URL to a PeerCast server to execute arbitrary
code.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All PeerCast users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/peercast-0.1212"

Title: cpio: Directory traversal vulnerability
Date: June 20, 2005
Bugs: #90619
ID: 200506-16
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
cpio contains a flaw which may allow a specially crafted cpio archive
to extract files to an arbitrary directory.
Background
==========
cpio is a file archival tool which can also read and write tar files.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/cpio < 2.6-r3 >= 2.6-r3
Description
===========
A vulnerability has been found in cpio that can potentially allow a
cpio archive to extract its files to an arbitrary directory of the
creator's choice.
Impact
======
An attacker could create a malicious cpio archive which would create
files in arbitrary locations on the victim's system. This issue could
also be used in conjunction with a previous race condition
vulnerability (CAN-2005-1111) to change permissions on files owned by
the victim.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All cpio users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/cpio-2.6-r3"
