Please backport your fixes for the following CVE reports:

CVE-2010-4351:
The JNLP SecurityManager in IcedTea (IcedTea.so) 1.7 before 1.7.7, 1.8 before
1.8.4, and 1.9 before 1.9.4 for Java OpenJDK returns from the checkPermission
method instead of throwing an exception in certain circumstances, which might
allow context-dependent attackers to bypass the intended security policy by
creating instances of ClassLoader.

CVE-2011-0025:
IcedTea 1.7 before 1.7.8, 1.8 before 1.8.5, and 1.9 before 1.9.5 does not
properly verify signatures for JAR files that (1) are "partially signed" or
(2) signed by multiple entities, which allows remote attackers to trick users
into executing code that appears to come from a trusted source.

To help me keep track of these fixes, please keep 'PRSC' somewhere in the
subject line of your emails.

Thanks,
