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

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*"
