-- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of Microsoft Windows Media Player. User
interaction is required to exploit this vulnerability in that the
target must visit a malicious page or open a malicious file.
The specific flaw exists during the parsing of malformed skin files
(WMZ). A size compressed / decompressed size mismatch can result in an
under allocated heap buffer which can be leveraged by an attacker to
eventually execute arbitrary code under the context of the current
user.
