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         < 1.5.0.10                   >= 1.5.0.10
                                                          *>= 1.4.2.13
     dev-java/sun-jdk         < 1.4.2.13                   >= 1.5.0.10
                                                          *>= 1.4.2.13
  2  dev-java/sun-jre-bin     < 1.5.0.10                   >= 1.5.0.10
                                                          *>= 1.4.2.13
     dev-java/sun-jre-bin     < 1.4.2.13                   >= 1.5.0.10
                                                          *>= 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 ">=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 ">=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*"
