Description

Microsoft's ASN.1 implementation contains a flaw that may allow a malicious user to cause denial-of-service conditions or possibly execute arbitrary code. The issue is triggered when a specially crafted authentication request is sent to the ASN.1 parser, causing it to free memory that has already been freed. It is possible that the flaw may allow memory corruption, denial of service, or the execution of arbitrary code, resulting in a loss of confidentiality, integrity, and/or availability.
