Yesterday, Microsoft found a flaw in MS-Word. Today, they discovered a new flaw in a different software. This time, it is not part of their Office suite. It is on their media player.

eEye Digital Security says that the problem is a buffer overflow error. The error is located on the file WMVCORE.DLL. The error occurs when long “REF HREF” tags are produced in the process of a .asx file.

Therefore, users should should not open .asx files for the meantime.
