Synopsis

The remote directory service is affected by multiple vulnerabilities.

Description

The remote host is running the Sun Java System Directory Proxy Server, an LDAP application-layer protocol gateway. It is typically provided with Sun Java System Directory Server Enterprise Edition.

The installed version of Sun Java System Directory Proxy Server is older than 6.3.1.1 and thus affected by multiple flaws :

- Under certain conditions, simultaneous long binds are incorrectly assigned the same back-end connection. An attacker may exploit this vulnerability to hijack an authenticated user's session and perform unauthorized operations. (CVE-2009-4440)
- 'SO_KEEPALIVE' socket option is not enabled, making it possible for a remote attacker to trigger a denial of service condition by exhausting available connection slots. (CVE-2009-4441)
- 'max-client-connections' configuration setting is not correctly implemented, making it possible for a remote attacker to trigger a denial of service condition.
(CVE-2009-4442)

- An unspecified vulnerability in 'psearch' functionality may allow an attacker to trigger a denial of service condition. (CVE-2009-4443)

Solution

Upgrade to Sun Java System Directory Server Enterprise Edition version 6.3.1 and then install patch 141958-01 or later.
