CVE-2008-2930
HighSummary
Red Hat Directory Server 7.1 przed SP7, Red Hat Directory Server 8 oraz Fedora Directory Server 1.1.1 umożliwiają zdalnym atakującym spowodowanie odmowy usługi poprzez wyspecjalizowane zapytania LDAP, które obciążają CPU i powodują przerwy w wyszukiwaniu. Problem ten dotyczy jednowątkowego podsystemu wyrażeń regularnych.
Risk Assessment
Odmowa usługi może prowadzić do zakłóceń w działaniu systemu, co wpływa na dostępność usług dla użytkowników. Atakujący mogą wykorzystać tę podatność do destabilizacji serwera katalogowego.
Recommendation
Zaleca się aktualizację do najnowszej wersji Red Hat Directory Server lub zastosowanie dostępnych poprawek, aby zniwelować ryzyko związane z tą podatnością.
