Sun(sm) Alert Notification
     * Sun Alert ID: 102895
     * Synopsis: Security Vulnerability in Sun Java System Directory
       Server May Cause Denial of Service (DoS)
     * Category: Security
     * Product: Sun Java System Directory Server 5.2, Sun Java System
       Directory Server Enterprise Edition, Sun ONE Directory Server 5.1
     * BugIDs: 6421049
     * Avoidance: Patch, Upgrade
     * State: Resolved
     * Date Released: 01-May-2007
     * Date Closed: 01-May-2007
     * Date Modified: 

1. Impact

   A local or remote unprivileged user may be able to cause the Sun Java
   System Directory Server to crash. This is a Denial of Service (DoS)
   due to a "Ber decoding" issue in the LDAP Software Development Kit
   (SDK) for C.

2. Contributing Factors

   This issue can occur in the following releases for all platforms
   (Solaris 8, 9, and 10 on Solaris SPARC and Solaris x86 Platforms,
   Linux, Windows, HP-UX, and AIX):

   Native Package Versions:
     * Sun Java System Directory Server 5 2003Q4 (5.2)
     * Sun Java System Directory Server 5 2004Q2 (5.2 Patch 2)
     * Sun Java System Directory Server 5 2005Q1 (5.2 Patch 3)
     * Sun Java System Directory Server 5 2005Q4 (5.2 Patch 4)

   PatchZIP (Compressed Archive) versions:
     * Sun ONE Directory Server 5.1
     * Sun Java System Directory Server 5.2
     * Sun Java System Directory Server 5.2 Patch 2
     * Sun Java System Directory Server 5.2 Patch 3
     * Sun Java System Directory Server 5.2 Patch 4

   without Sun Java System Directory Server version 5.2 Patch 5 (see
   "Resolution" section).

   To determine the version of Directory Server running on a system, the
   following command can be used:
    $ cd <installation directory>/bin/slapd/server[/64]
    $ ./ns-slapd -V -D <instance-directory>

3. Symptoms

   Should the described issue occur, the Directory Server will crash with
   a message in the error log similar to the following (the malloc()
   bytes vary):
    [03/May/2006:08:44:30 +0200] - ERROR<5130> - Resource Limit - conn=-1 op=-1
 msgId=-1-
    Memory allocation error  malloc of 1879048193 bytes failed; errno 11
    The server has probably allocated all available virtual memory. To solve th
is problem, make
    more virtual memory available to your server, or reduce the size of the ser
ver's `Maximum
    Entries in Cache' (cachesize) or `Maximum DB Cache Size' (dbcachesize) para
meters.
    can't recover; calling exit(1) 

4. Relief/Workaround

   There is no workaround for this issue. Please see Resolution section
   below.
