The sample is a PDF document that contains a critical heuristic firing for CVE_2008_2551, indicating it exploits a vulnerability to download a payload. The embedded URL 'http://c6.community.alice.it/download/DownloaderActiveX.cab#Version=1,0,0,1' likely points to the exploit component, while 'http://artisanballoonz.com/system/system.exe' is a suspicious executable download URL.
