A security flaw thought to have been fixed by Adobe in October 2011 has reappeared thanks to a new vulnerability involving Flash Player browser plug-ins.
The as yet unpatched vulnerability creates a means to seize control of webcams without permission before siphoning off video and audio from victims' PCs. The clickjack-style flaw was uncovered by security consultant Egor Homakov, who developed a harmless proof-of-concept exploit to underline his concerns and push for an early fix.
