Description

The First4Internet XCP DRM software used to playback Sony copy-protected music CDs contains a flaw that may allow a malicious user to arbitrary manipulate local files and processes. The problem is that the 'aries.sys' driver hides any files, registry keys and/or processes with a name that starts with '$sys$', which may allow a malicious user to hide certain activities on a system that uses XCP resulting in a loss of integrity.
