1. Impact

A security vulnerability in the Sun Java System Directory Server (ns-slapd and slapd.exe) may allow a remote unprivileged user to crash the Directory Server process via crafted LDAP search requests, thereby leading to a Denial of Service (DoS) condition.

2. Contributing Factors

This issue can occur in the following releases for Solaris 9 and 10 on SPARC platform, Solaris 10 on x64 platform, Linux, Windows, and HP-UX:

PatchZIP (Compressed Archive) and Native package versions:

• Sun Directory Server Enterprise Edition 7.0 without patch 143884-01

This issue can occur in the following releases for Solaris 9 and 10 on SPARC platform, x86 and x64 platforms, Linux, Windows, and HP-UX:

PatchZIP (Compressed Archive) and Native package versions:

• Sun Java System Directory Server Enterprise Edition 6.3.1 without patch 143463-01
• Sun Java System Directory Server Enterprise Edition 6.3
• Sun Java System Directory Server Enterprise Edition 6.2
• Sun Java System Directory Server Enterprise Edition 6.1
• Sun Java System Directory Server Enterprise Edition 6.0

This issue can occur in the following releases for Solaris 9 and 10 on SPARC, x86 and x64 platforms, Linux, Windows, AIX and HP-UX:

PatchZIP (Compressed Archive) and Native package versions:

• Sun Java System Directory Server 5.2 without patch 143462-01

To determine the version of Directory Server running on a system, the following command can be run:

For Directory Server 5.2:

On Solaris, Linux, AIX and HP-UX systems:

$ cd <installation directory>/bin/slapd/server
$ ./ns-slapd -V -D <instance-directory>

On 64-bit Solaris:

$ cd <installation directory>/bin/slapd/server/64
$ ./ns-slapd -V -D <instance-directory>

On 64-bit HP-UX:

$ cd <installation directory>/bin/slapd/server/pa20_64
$ ./ns-slapd -V -D <instance-directory>

On Windows systems:
If the output contains the version string 5.2, the system is affected by this issue.

For Directory Server 6.x:

On Solaris, Linux and HP-UX systems (including 64-bit systems):

$ cd <installation directory>/ds6/bin
$ ./dsadm -V

On Windows systems:

cd <installation directory>\ds6\bin
dsadm.exe -V

If the output contains the version string 6.0, 6.1, 6.2, 6.3 or 6.3.1, the system is affected by this issue.

For Directory Server 7.0:

On Solaris, Linux and HP-UX systems (including 64-bit systems):

$ cd <installation directory>/bin
$ ./dsadm -V

On Windows systems:

cd <installation directory>\bin
dsadm.exe -V

If the output contains the version string 7.0, the system is affected by this issue.

3. Symptoms

If the described issue occurs, the Directory Server may crash, resulting in the service being no longer available. If the system is configured to dump core, the stack trace may be observed to be similar to the following:

parse_LDAPProxyAuth ()
core_get_proxyauth_dn ()
common_core_set_pb ()
search_core_set_pb ()
ldap_decode_search ()
ldap_parse_request ()
process_ldap_operation_using_core_api ()
ldap_frontend_main_using_core_api ()

4. Workaround

There is no workaround available for this issue.
