IBM Tivoli Directory Server < 6.1.0.59 / 6.2.0.34 / 6.3.0.26 with GSKit < 7.0.4.48 / 8.0.50.16 X.509 Certificate Chain DoS

High Nessus Plugin ID 72220

Synopsis

The version of IBM Tivoli Directory Server and GSKit is affected by a denial of service vulnerability.

Description

The remote host is running a version of IBM Tivoli Directory Server 6.1.0.x prior to 6.1.0.59, 6.2.0 prior to 6.2.0.34, or 6.3.0.x prior to 6.3.0.26, and a version of IBM Global Security Kit (GSKit) 7.0.x prior to 7.0.4.48 or 8.0.50.x prior to 8.0.50.16. It is, therefore, affected by a denial of service vulnerability due to a flaw in the GSKit library. An attacker can exploit this vulnerability via a malformed X.509 certificate chain to cause an application crash or hang.

Solution

Install the appropriate fix based on the vendor's advisory :

- 6.1.0.59-ISS-ITDFS-IF0059
- 6.2.0.34-ISS-ITDFS-IF0034
- 6.3.0.26-ISS-ITDFS-IF0026

Alternatively, upgrade GSKit to 7.0.4.48 or 8.0.50.16.
