3. Description:

These packages provide the OpenJDK 6 Java Runtime Environment and the
OpenJDK 6 Software Development Kit.

A denial of service flaw was found in the way certain strings were
converted to Double objects. A remote attacker could use this flaw to cause
Java-based applications to hang, for instance if they parse Double values
in a specially-crafted HTTP request. (CVE-2010-4476)

All users of java-1.6.0-openjdk are advised to upgrade to these updated
packages, which resolve this issue. All running instances of OpenJDK Java
must be restarted for the update to take effect.
