    Summary: Authentication Buffer Overflows

    Details: Due to bad usage of the base64 decode function to a stack-based buffer without checking the data length, it was possible for a malicious HTTP server to overflow the client during NTLM negotiation and for an FTP server to overflow the client during krb4 negotiation. The [announcement](http://www.idefense.com/application/poi/display?id=202) of this flaw was done without contacting us.
