CVE-2006-4520
HighSummary
W ncp w Novell eDirectory przed wersją 8.7.3 SP9 oraz 8.8.x przed wersją 8.8.1 FTF2 występuje problem z obsługą fragmentów NCP o ujemnej długości, co może prowadzić do awarii demona. Atakujący zdalnie mogą spowodować odmowę usługi poprzez zapisanie danych w pliku dziennika.
Risk Assessment
Organizacja może doświadczyć przerwy w dostępności usług z powodu awarii systemu, co może prowadzić do utraty danych lub zakłócenia działalności. Potencjalne ataki mogą wpłynąć na reputację i zaufanie klientów.
Recommendation
Zaleca się aktualizację Novell eDirectory do najnowszej wersji, aby usunąć tę podatność. Należy również monitorować logi systemowe w celu wykrycia potencjalnych prób ataków.

Original NVD description (English source)
ncp in Novell eDirectory before 8.7.3 SP9, and 8.8.x before 8.8.1 FTF2, does not properly handle NCP fragments with a negative length, which allows remote attackers to cause a denial of service (daemon crash) when the heap is written to a log file.
