CVE-2008-5534
HighSummary
ESET NOD32 Antivirus w wersjach 3662 i prawdopodobnie 3440, w przypadku użycia Internet Explorera 6 lub 7, pozwala zdalnym atakującym na ominięcie wykrywania złośliwego oprogramowania w dokumencie HTML. Możliwe jest to poprzez umieszczenie nagłówka MZ na początku oraz modyfikację nazwy pliku, aby nie miała rozszerzenia, miała rozszerzenie .txt lub .jpg.
Risk Assessment
Organizacja może być narażona na ataki z wykorzystaniem złośliwego oprogramowania, które nie zostanie wykryte przez ESET NOD32, co może prowadzić do utraty danych lub kompromitacji systemów.
Recommendation
Zaleca się aktualizację ESET NOD32 do najnowszej wersji oraz monitorowanie i skanowanie plików HTML pod kątem nietypowych nagłówków i rozszerzeń.

Original NVD description (English source)
ESET NOD32 Antivirus 3662 and possibly 3440, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.
