Descriptions

Multiple integer overflows in Microsoft ASN.1 library (MSASN1.DLL), as used in LSASS.EXE, CRYPT32.DLL, and other Microsoft executables and libraries on Windows NT 4.0, 2000, and XP, allow remote attackers to execute arbitrary code via ASN.1 BER encodings with (1) very large length fields that cause arbitrary heap data to be overwritten, or (2) modified bit strings.

Múltiples desbordamientos de enteros en la librería ASN.1 de Microsoft (MSASN1.DLL), usada en LSASS.EXE, CRYPT32.DLL, y otros ejecutables de Microsoft y librerías en Windows NT/2000/XP, permite a atacantes remotos ejecutar código arbitrario mediante codificaciones ASN.1 BER con campos de longitud muy largos que hace que se sobreescriban datos arbitrarios del montón.
