IBM Security Directory Server < 6.1.0.61 / 6.2.0.36 / 6.3.0.30 / 6.3.1.2 with GSKit < 7.0.4.50 / 8.0.50.20 SSL CPU Utilization DoS

High Nessus Plugin ID 80482

Synopsis

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

Description

The remote host is running a version of IBM Security Directory Server (formerly IBM Tivoli Directory Server) and a version of IBM Global Security Kit (GSKit) that is affected by a denial of service vulnerability due to a flaw in the GSKit library. An attacker can exploit this issue via a specially-crafted SSL to use excessive CPU resources resulting in the host to become unresponsive.

Solution

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

- 6.1.0.61-ISS-ITDS
- 6.2.0.36-ISS-ITDS
- 6.3.0.30-ISS-ITDS
- 6.3.1.2-ISS-ISDS

Alternatively, upgrade GSKit to 7.0.4.50 or 8.0.50.20.
