CVE-2008-5284
HighSummary
Serwer WWW w oprogramowaniu IEA Software RadiusNT i RadiusX w wersjach 5.1.38 i wcześniejszych, Emerald w wersjach 5.0.49 i wcześniejszych, Air Marshal w wersjach 2.0.4 i wcześniejszych oraz klient testowy Radius (Radlogin) w wersji 4.0.20 i wcześniejszych, pozwala zdalnym atakującym na spowodowanie odmowy usługi (crash) poprzez nagłówek HTTP Content-Length z wartością ujemną, co prowadzi do nadpisania pamięci jednym bajtem z użyciem NULL terminatora.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zdalnego zablokowania serwera, co może prowadzić do przestojów w działaniu usług i utraty dostępności dla użytkowników.
Recommendation
Zaleca się aktualizację oprogramowania do wersji 5.1.44 dla RadiusNT i RadiusX, 5.0.52 dla Emerald, 2.0.8 dla Air Marshal oraz 4.0.20 dla Radlogin, aby usunąć tę podatność.

Original NVD description (English source)
The web server in IEA Software RadiusNT and RadiusX 5.1.38 and other versions before 5.1.44, Emerald 5.0.49 and other versions before 5.0.52, Air Marshal 2.0.4 and other versions before 2.0.8, and Radius test client (aka Radlogin) 4.0.20 and earlier, allows remote attackers to cause a denial of service (crash) via an HTTP Content-Length header with a negative value, which triggers a single byte overwrite of memory using a NULL terminator.
