CVE-2011-2821
HighSummary
W bibliotece libxml2, używanej w Google Chrome przed wersją 13.0.782.215, występuje podatność na podwójne zwolnienie pamięci. Umożliwia to zdalnym atakującym spowodowanie odmowy usługi lub potencjalnie innego nieokreślonego wpływu poprzez spreparowane wyrażenie XPath.
Risk Assessment
Podatność ta może prowadzić do awarii przeglądarki, co wpływa na dostępność usług dla użytkowników. Istnieje również ryzyko wykorzystania tej luki do przeprowadzenia innych ataków.
Recommendation
Zaleca się aktualizację Google Chrome do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, monitorowanie i analiza ruchu sieciowego mogą pomóc w wykrywaniu prób wykorzystania tej luki.
