Adobe today sounded an alarm for a new zero-day flaw in its PDF Reader/Acrobat software, warning that hackers are actively exploiting the vulnerability in-the-wild. Details on the vulnerability are not yet public but the sudden warning from Adobe is a sure sign that rigged PDF documents are being used by malicious hackers to take complete control of machines with the latest versions of Adobe Reader/acrobat installed. Adobe said it cannot offer any pre-patch advice to help users thwart the attacks. It targets Windows users, affects Acrobat 8 and 9, exploits multiple versions at once and bypasses DEP and ASLR.
