Description: This security update resolves a privately reported vulnerability in Microsoft MPEG Layer-3 audio codecs. The vulnerability could allow remote code execution if a user opened a specially crafted AVI file containing an MPEG Layer-3 audio stream. 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. The security update addresses the vulnerability by correcting the way that the Microsoft MPEG Layer-3 audio codecs decode the MPEG Layer-3 audio stream in specially crafted AVI files.
