Novell eDirectory Heap Overflow and Denial of Service Vulnerabilities

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

1. Due to heap overflow errors when processing update replica verbs (Opcode 0x23 and 0x24), which could be exploited by attackers to crash an affected service or execute arbitrary code.

2. Due to a heap overflow error when handling the DSV_READ verb (Opcode 0x0F), which could be exploited by attackers to crash an affected service or execute arbitrary code.

3. Due to an error when handling an invalid HTTP Content-Length field value, which could be exploited to cause a crash.
