Three Gentoo Linux Security Advisories:
1. GLSA 200602-04 - Xpdf, Poppler: Heap overflow
2. GLSA 200602-05 - KPdf: Heap based overflow
3. GLSA 200602-07 - Sun JDK/JRE: Applet privilege escalation
Detail
======
1. Dirk Mueller has reported a vulnerability in Xpdf. It is caused by a
missing boundary check in the splash rasterizer engine when handling
PDF splash images with overly large dimensions.
2. KPdf includes Xpdf code to handle PDF files. Dirk Mueller discovered
that the Xpdf code is vulnerable a heap based overflow in the splash
rasterizer engine.
3. Applets executed using JRE or JDK can use "reflection" APIs functions
to elevate its privileges beyond the sandbox restrictions. Adam Gowdiak
discovered five vulnerabilities that use this method for privilege
escalation. Two more vulnerabilities were discovered by the vendor.
Peter Csepely discovered that Web Start Java applications also can an
escalate their privileges.

Title: Xpdf, Poppler: Heap overflow
Date: February 12, 2006
Bugs: #120985
ID: 200602-04
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Xpdf and Poppler are vulnerable to a heap overflow that may be
exploited to execute arbitrary code.
Background
==========
Xpdf is a PDF file viewer that runs under the X Window System. Poppler
is a PDF rendering library based on the Xpdf 3.0 code base.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/xpdf < 3.01-r7 >= 3.01-r7
2 app-text/poppler < 0.5.0-r4 >= 0.5.0-r4
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Dirk Mueller has reported a vulnerability in Xpdf. It is caused by a
missing boundary check in the splash rasterizer engine when handling
PDF splash images with overly large dimensions.
Impact
======
By sending a specially crafted PDF file to a victim, an attacker could
cause an overflow, potentially resulting in the execution of arbitrary
code with the privileges of the user running the application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Xpdf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/xpdf-3.01-r7"
All Poppler users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.0-r4"

Title: KPdf: Heap based overflow
Date: February 12, 2006
Bugs: #121375
ID: 200602-05
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
KPdf includes vulnerable Xpdf code to handle PDF files, making it
vulnerable to the execution of arbitrary code.
Background
==========
KPdf is a KDE-based PDF viewer included in the kdegraphics package.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 kde-base/kdegraphics < 3.4.3-r4 >= 3.4.3-r4
2 kde-base/kpdf < 3.4.3-r4 >= 3.4.3-r4
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
KPdf includes Xpdf code to handle PDF files. Dirk Mueller discovered
that the Xpdf code is vulnerable a heap based overflow in the splash
rasterizer engine.
Impact
======
An attacker could entice a user to open a specially crafted PDF file
with Kpdf, potentially resulting in the execution of arbitrary code
with the rights of the user running the affected application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All kdegraphics users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.4.3-r4"
All Kpdf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.3-r4"

Title: Sun JDK/JRE: Applet privilege escalation
Date: February 15, 2006
Bugs: #122156
ID: 200602-07
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Sun's Java Development Kit (JDK) and Java Runtime Environment (JRE) do
not adequately constrain applets from privilege escalation and
arbitrary code execution.
Background
==========
Sun's JDK and JRE provide interpreters for Java Applets in a sandboxed
environment. These implementations provide the Java Web Start
technology that can be used for easy client-side deployment of Java
applications.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/sun-jdk < 1.4.2.10 >= 1.4.2.10
2 dev-java/sun-jre-bin < 1.4.2.10 >= 1.4.2.10
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Applets executed using JRE or JDK can use "reflection" APIs functions
to elevate its privileges beyond the sandbox restrictions. Adam Gowdiak
discovered five vulnerabilities that use this method for privilege
escalation. Two more vulnerabilities were discovered by the vendor.
Peter Csepely discovered that Web Start Java applications also can an
escalate their privileges.
Impact
======
A malicious Java applet can bypass Java sandbox restrictions and hence
access local files, connect to arbitrary network locations and execute
arbitrary code on the user's machine. Java Web Start applications are
affected likewise.
Workaround
==========
Select another Java implementation using java-config.
Resolution
==========
All Sun JDK users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.10"
All Sun JRE users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.10"
