CVE-2008-4226
HighSummary
Przepełnienie całkowitej liczby w funkcji xmlSAX2Characters w libxml2 w wersji 2.7.2 umożliwia atakującym, zależnie od kontekstu, spowodowanie odmowy usługi (uszkodzenie pamięci) lub potencjalne wykonanie dowolnego kodu poprzez dużą dokumentację XML.
Risk Assessment
Ryzyko dla organizacji polega na możliwości wystąpienia odmowy usługi lub wykonania złośliwego kodu, co może prowadzić do poważnych konsekwencji dla integralności i dostępności systemów.
Recommendation
Zaleca się aktualizację libxml2 do najnowszej wersji, aby zniwelować ryzyko związane z tą podatnością oraz monitorowanie aplikacji przetwarzających dokumenty XML.
