Sun(sm) Alert Notification
     * Sun Alert ID: 102461
     * Synopsis: Memory Leak in NSS May Cause the System to Hang or Panic
     * Category: Security, Availability
     * Product: Sun Java Enterprise System 2003Q4, Sun Java Enterprise
       System 2005Q1, Sun Java Enterprise System 2004Q2
     * BugIDs: 6421471
     * Avoidance: Workaround, Patch
     * State: Resolved

1. Impact

   With Sun Java Enterprise System 2003Q4, 2004Q2 and 2005Q1 and patch
   119209-07, 119211-07 or 119213-07 (for SPARC) or patch
   119212-07 or 119214-07 (for x86) or patch 121656-07 (for
   Linux) installed, Network Security Services (NSS) will leak 256 bytes
   of memory per RSA cryptographic operation. After a certain amount of
   time, this causes the system to run out of memory and may lead to a
   system hang or panic.

   NSS is an open source project, and it provides SSL, SMIME and
   certificate management services to Sun Java Enterprise System.
