CVE-2011-1528
HighSummary
Funkcja krb5_ldap_lockout_audit w Centrum Dystrybucji Kluczy (KDC) w MIT Kerberos 5 w wersjach od 1.8 do 1.8.4 oraz od 1.9 do 1.9.1, przy użyciu backendu LDAP, pozwala zdalnym atakującym na spowodowanie odmowy usługi (awaria asercji i zakończenie działania demona) poprzez nieokreślone wektory, związane z funkcją locked_check_p.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zakłócenia działania systemu, co może prowadzić do przerwy w dostępności usług opartych na Kerberosie. To może wpłynąć na bezpieczeństwo i ciągłość działania organizacji.
Recommendation
Zaleca się aktualizację do najnowszej wersji MIT Kerberos 5, aby usunąć tę podatność. Należy również monitorować systemy pod kątem nieautoryzowanych prób dostępu.
