eEye Security Advisory – eEye Digital Security has discovered a critical vulnerability in Microsoft’s ASN.1 library (MSASN1.DLL) that would allow an attacker to overwrite heap memory on a susceptible machine and cause the execution of arbitrary code. Because this library is widely used by Windows security subsystems, the vulnerability is exposed through an array of avenues, including Kerberos, NTLMv2 authentication, and applications that make use of certificates (SSL, digitally-signed e-mail, signed ActiveX controls, etc.).
