A Security Vulnerability in the Sun Java System Server, Related to the Directory Proxy Server, May Lead to a Denial of Service (DoS) Condition

1. Impact

A Security Vulnerability in Sun Java System Directory Proxy Server (a component of Sun Java System Directory Server Enterprise Edition) may allow a local or remote unprivileged user to make the Directory Proxy Server unresponsive to certain requests implying a JDBC backend. This is a type of Denial of Service (DoS).

2. Contributing Factors

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

PatchZIP (Compressed Archive) and Native package versions:
  • Sun Java System Directory Server Enterprise Edition 6.0
  • Sun Java System Directory Server Enterprise Edition 6.1
  • Sun Java System Directory Server Enterprise Edition 6.2
  • Sun Java System Directory Server Enterprise Edition 6.3
without patches 125276-08, 125277-08, 125278-08, 125309-08, 125311-08, 126748-05, 126749-05, 126750-05, 126751-05, 126753-05, 126752-05 (as listed in the "Resolution" section below).

Notes:

1. Solaris 8 is not affected by this issue.
2. Sun Java System Directory Server Enterprise Edition 5.x is not affected by this issue.

To determine the version of Directory Proxy Server running on a system, the following command can be run: 
$ dpconf -V
[dpconf]
dpconf : 6.3

3. Symptoms

Specifically crafted LDAP requests can put the Directory Proxy Server into a state where any further request implying a JDBC backend will become unresponsive until restart of the Directory Proxy Server.

4. Workaround

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

5. Resolution
