The security issue is caused due to IBM Java skipping illegal UTF-8 byte sequences instead of e.g. replacing them with "\uFFFD", which can be exploited to e.g. bypass certain filtering mechanisms. SOLUTION: Reportedly, this will be fixed in version 1.4.2 SR13 FP6, 5.0.0 SR12, and 6.0.0 SR9. PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
