Description: Some vulnerabilities have been reported in Windows Media Format Runtime, which potentially can be exploited by malicious people to compromise a user's system.
1) A boundary error within the handling of "REF HREF" tags in ASX playlists can be exploited to cause a limited heap-based buffer overflow via an overly long string with an invalid URL.
2) A boundary error within the processing of Advanced Systems Format (ASF) files can be exploited to cause a buffer overflow via a specially crafted ASF file.
Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
