CVE-2020-1487
HighSummary
Podatność CVE-2020-1487 dotyczy ujawnienia informacji, które występuje, gdy Media Foundation niewłaściwie obsługuje obiekty w pamięci. Atakujący, który skutecznie wykorzysta tę podatność, może uzyskać informacje, które pozwolą mu na dalsze kompromitowanie systemu użytkownika.
Risk Assessment
Ryzyko dla organizacji polega na możliwości uzyskania przez atakującego poufnych informacji, co może prowadzić do dalszych ataków na systemy użytkowników. Wymaga to jednak, aby użytkownik otworzył specjalnie przygotowany plik z zainfekowanej strony internetowej lub wiadomości.
Recommendation
Zaleca się zainstalowanie aktualizacji, która poprawia sposób, w jaki Media Foundation obsługuje obiekty w pamięci, aby zminimalizować ryzyko związane z tą podatnością. Dodatkowo, użytkownicy powinni być edukowani na temat zagrożeń związanych z otwieraniem plików z nieznanych źródeł.

Original NVD description (English source)
An information disclosure vulnerability exists when Media Foundation improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system. To exploit this vulnerability, an attacker would have to log onto an affected system and open a specially crafted file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file. The update addresses the vulnerability by correcting how Media Foundation handles objects in memory.
