Adobe on Thursday revealed a "critical" vulnerability impacting its Shockwave Player. The flaw, present in Shockwave and earlier versions for Windows and Macintosh, could allow an attacker to assume total system control, according to a security bulletin. Though Adobe is not aware of any in-the-wild attacks, the bug has been disclosed publicly. The company did not say when a fix would be released. The current version of Shockwave was released in August to plug 20 holes. — DK
