Adobe issued an alert late Friday night to warn about zero-day attacks against an unpatched vulnerability in its Reader and Flash Player software products. The vulnerability, described as critical, affects Adobe Flash Player 10.0.45.2 and earlier versions for Windows, Macintosh, Linux and Solaris operating systems. Adobe recommends deleting, renaming, or removing access to the authplay.dll file that ships with Adobe Reader and Acrobat 9.x. This will mitigate the threat but users will experience a non-exploitable crash.
