Technical Description

Multiple vulnerabilities have been identified in Redhat Directory Server, which could be exploited by remote attackers to disclose sensitive information, cause a denial of service or execute arbitrary code.

The first issue is caused by buffer overflow errors in various CGI applications when processing malformed "Accept-Language" HTTP headers, which could be exploited by remote attackers to crash an affected application or execute arbitrary code with "root" privileges.

The second vulnerability is caused by input validation errors in the Directory Server Administration Express and Directory Server Gateway (DSGW) web interface, which could allow cross site scripting attacks.

The third issue is caused by unspecified memory leaks, which could allow an unauthenticated remote attacker to exhaust all available memory resources.

The fourth vulnerability is caused by an error when handling LDAP search requests with patterns, which could allow attackers to cause Directory Server to use a large amount of CPU time.
