Description: Multiple vulnerabilities have been reported in Novell eDirectory, which can be exploited by malicious people to compromise a vulnerable system. 1) A boundary error within the NCP engine when processing NCP over IP can be exploited to cause a heap-based buffer overflow via a specially crafted packet. Successful exploitation may allow execution of arbitrary code. 2) An integer overflow error within the "evtFilteredMonitorEventsRequest()" function can be exploited to cause a heap-based buffer overflow via a specially crafted request. Successful exploitation may allow execution of arbitrary code. 3) An invalid free in the "evtFilteredMonitorEventsRequest()" function can be exploited via a specially crafted request. Successful exploitation may allow execution of arbitrary code. 4) An error exists in the NCP engine when processing fragmented packets. This can be exploited to crash the eDirectory service or cause the eDirectory log to grow thereby consuming available disk space by sending a specially crafted fragmented request. The vulnerabilities are reported in versions 8.7.3, 8.8, and 8.8.1. Other versions may also be affected.
