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.
The first issue is caused by 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.
The second vulnerability is caused by 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.
The third issue is caused by an error when handling an invalid HTTP Content-Length field value, which could be exploited to cause a crash.
The fourth vulnerability is caused by an error when handling an oversized HTTP Accept-Language value, which could be exploited to cause a crash.
