TITLE: Sun Java System Directory Server LDAP Request Buffer Overflow

SECUNIA ADVISORY ID: SA14960

VERIFY ADVISORY: http://secunia.com/advisories/14960/

CRITICAL: Moderately critical

IMPACT: DoS, System access

WHERE: >From local network

SOFTWARE: Sun Java System Directory Server 5.x http://secunia.com/product/1520/

DESCRIPTION: Sun has acknowledged a vulnerability in Sun ONE/Java System Directory Server, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the access control implementation when handling LDAP requests. This can be exploited to cause a buffer overflow via a specially crafted, invalid LDAP request.

Successful exploitation crashes the LDAP service or allows execution of arbitrary code with the privileges of the LDAP process.

SOLUTION: Apply patches.
