Description:
eEye Digital Security has discovered some vulnerabilities in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerabilities are caused due to boundary errors in the Microsoft ASN.1 Library ("msasn1.dll") during ASN.1 BER decoding. These can be exploited via various security services (e.g. Kerberos and NTLMv2 authentication) and applications using certificates to cause a buffer overflow by sending malformed ASN.1 data to the service or application.

Successful exploitation may allow execution of arbitrary code on an affected system with SYSTEM privileges.
