Synopsis
========

Sun Java Development Kit (JDK) and Java Runtime Environment (JRE)
contain a memory corruption flaw that allows the applets to gain
elevated privileges potentially leading to the execute of arbitrary
code.

Background
==========

The Sun Java Development Kit (JDK) and the Sun Java Runtime Environment
(JRE) provide the Sun Java platform.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/sun-jdk lt; 1.5.0.10 gt;= 1.5.0.10
*gt;= 1.4.2.13
dev-java/sun-jdk lt; 1.4.2.13 gt;= 1.5.0.10
*gt;= 1.4.2.13
2 dev-java/sun-jre-bin lt; 1.5.0.10 gt;= 1.5.0.10
*gt;= 1.4.2.13
dev-java/sun-jre-bin lt; 1.4.2.13 gt;= 1.5.0.10
*gt;= 1.4.2.13
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

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

A anonymous researcher discovered that an error in the handling of a
GIF image with a zero width field block leads to a memory corruption
flaw.

Impact
======

An attacker could entice a user to run a specially crafted Java applet
or application that would load a crafted GIF image, which could result
in escalation of privileges and unauthorized access to system
resources.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Sun Java Development Kit 1.5 users should upgrade to the latest
version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-java/sun-jdk-1.5.0.10"

All Sun Java Development Kit 1.4 users should upgrade to the latest
version:

# emerge --sync
# emerge --ask --oneshot --verbose "=dev-java/sun-jdk-1.4.2*"

All Sun Java Runtime Environment 1.5 users should upgrade to the latest
version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-java/sun-jre-bin-1.5.0.10"

All Sun Java Runtime Environment 1.4 users should upgrade to the latest
version:

# emerge --sync
# emerge --ask --oneshot --verbose "=dev-java/sun-jre-bin-1.4.2*"
