Windows Media Player is prone to a buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data. Attackers may attempt to exploit this issue by coercing users to visit a malicious website or to access malicious ASF files. Successfully exploiting this issue allows remote attackers to execute arbitrary machine code in the context of the user running the affected application. This facilitates the remote compromise of affected computers.

Run all software as a nonprivileged user with minimal access rights.
To limit the potential damage that a successful exploit may achieve, run all nonadministrative software as a regular user with the least amount of privileges required to successfully operate.
Do not accept or execute files from untrusted or unknown sources.
To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.
Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Implement multiple redundant layers of security.
Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Microsoft has released an advisory along with fixes. Please see the references for more information.
