Being a designer, you’re at the mercy of what your clients sends, regardless of what format. Sometimes you may get notes via Excel, PDF, Word, on a napkin, ramblings in a voicemail… I could keep going, but I think you get the point. In all seriousness, if you use Acrobat to view PDFs, you may want to update your software, as Adobe just released a security patch.
“There are reports that one of the vulnerabilities, CVE-2011-0611, is being actively exploited in the wild against both Adobe Flash Player, and Adobe Reader and Acrobat, as well as via a Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft Excel (.xls) file delivered as an email attachment targeting the Windows platform,” the company stated in a security advisory.
The patch was released for Adobe Reader X for Mac and Adobe Reader, Adobe Acrobat and Adobe Acrobat X for Windows and Mac operating systems. Also, the patch was released ahead of schedule, possibly due to the severity of the vulnerability.
It should be noted that the vulnerability does not effect Adobe Reader for Unix or Android.
