Novell eDirectory Buffer Overflow and Denial of Service Vulnerabilities

Multiple vulnerabilities have been identified in Novell eDirectory, which could be exploited by remote attackers to cause a denial of service or compromise a vulnerable system.

1. An error in NDSD when processing a bad verb, which could be exploited to crash an affected daemon.

2. A buffer overflow error in DHOST when processing malformed requests, which could be exploited by attackers to crash an affected process or execute arbitrary code.

3. Due to DHOST using predictable session cookies, which could allow attackers to bypass restrictions.

4. An error in DHOST when handling malformed requests sent by certain scanners, which could cause a vulnerable process to crash, creating a denial of service condition.
