CVE-2011-1142
HighSummary
W podatności CVE-2011-1142 występuje problem z konsumpcją stosu w funkcji dissect_ber_choice w analizatorze BER w Wireshark w wersjach 1.2.x do 1.2.15 oraz 1.4.x do 1.4.4. Może to umożliwić zdalnym atakującym spowodowanie odmowy usługi (nieskończona pętla) poprzez wykorzystanie samoodniesień wartości CHOICE ASN.1.
Risk Assessment
Organizacje mogą być narażone na ataki, które prowadzą do odmowy usługi, co może zakłócić działanie systemów monitorujących ruch sieciowy. W rezultacie, może to wpłynąć na zdolność do analizy i reagowania na incydenty bezpieczeństwa.
Recommendation
Zaleca się aktualizację Wireshark do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, monitorowanie i ograniczenie dostępu do analizatorów ruchu sieciowego może pomóc w zminimalizowaniu ryzyka.
