According to SUN it has been reported that: "the Java Secure Socket
Extension (JSSE) may incorrectly validate the digital certificate of a
web site. This may result in untrustworthy web sites being
authenticated for SSL transactions. The Java Plug-in and Java Web Start
may incorrectly validate the digital certificates of signed JAR files.
This may result in untrustworthy code being executed as trusted code."
From the JSSE changelog: "If an SSLContext was initialized
(SSLContext.init()) with an instance of the X509TrustManager
implementation, JSSE 1.0.3 incorrectly called the isClientTrusted()
method when making server trust decisions."

The changelog Java(tm) Secure Socket Extension 1.0.3_01 mentions this
vulnerability
