Microsoft Data Access Components Multiple Vulnerabilities

1. DSN Overflow Vulnerability

A remote code execution vulnerability exists in the way that Microsoft Data Access Components validates third-party API usage. This vulnerability could allow code execution if a user visited a specially crafted Web page. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

2.ADO Record Memory Vulnerability

A remote code execution vulnerability exists in the way that Microsoft Data Access Components validates memory allocation. This vulnerability could allow code execution if a user visited a specially crafted Web page. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
